摘要：
Based on e(+)e(-) collision data collected at center-of-mass energies from 2.000 to 3.080 GeV by the BESIII detector at the BEPCII collider, a partial wave analysis is performed for the process e(+)e(-) -> (KSKL0)-K-0 pi(0). The results allow the Born cross sections of the process e(+)e(-) -> (KSKL0)-K-0 pi(0), as well as its subprocesses e(+)e(-) -> K*(892)K-0(0) over bar and K-2*(1430)K-0(0) to be measured. The Born cross sections for e(+)e(-) -> (KSKL0)-K-0 pi(0) are consistent with previous measurements by BaBar, but with substantially improved precision. The Born cross section lineshape of the process e(+)e(- )-> K*(892)K-0(0) is consistent with a vector meson state around 2.2 GeV with a significance of 3.2 sigma. A Breit-Wigner fit determines its mass as M-Y = (2164.7 +/- 9.1 +/- 3.1) MeV/c(2) and its width as Gamma(Y) = (32.4 +/- 21.0 +/- 1.8) MeV.

摘要：
Based on data samples collected with the BESIII detector at the BEPCII collider, the process e^{+}e^{-}→Σ^{+}Σ[over ¯]^{-} is studied at center-of-mass energies sqrt[s]=2.3960, 2.6454, and 2.9000GeV. Using a fully differential angular description of the final state particles, both the relative magnitude and phase information of the Σ^{+} electromagnetic form factors in the timelike region are extracted. The relative phase between the electric and magnetic form factors is determined to be sinΔΦ=-0.67±0.29(stat)±0.18(syst) at sqrt[s]=2.3960 GeV, ΔΦ=55°±19°(stat)±14°(syst) at sqrt[s]=2.6454 GeV, and 78°±22°(stat)±9°(syst) at sqrt[s]=2.9000 GeV. For the first time, the phase of the hyperon electromagnetic form factors is explored in a wide range of four-momentum transfer. The evolution of the phase along with four-momentum transfer is an important input for understanding its asymptotic behavior and the dynamics of baryons.

摘要：
Based on 4.4 fb^{-1} of e^{+}e^{-} annihilation data collected at the center-of-mass energies between 4.60 and 4.70GeV with the BESIII detector at the BEPCII collider, the pure W-boson-exchange decay Λ_{c}^{+}→Ξ^{0}K^{+} is studied with a full angular analysis. The corresponding decay asymmetry is measured for the first time to be α_{Ξ^{0}K^{+}}=0.01±0.16(stat)±0.03(syst). This result reflects the noninterference effect between the S- and P-wave amplitudes. The phase shift between S- and P-wave amplitudes has two solutions, which are δ_{p}-δ_{s}=-1.55±0.25(stat)±0.05(syst) rad or 1.59±0.25(stat)±0.05(syst) rad.

摘要：
Based on a dataset of (27.12 +/- 0.10) x 10(8) psi(3686) events collected at the BESIII experiment, the absolute branching fractions of the three dominant Omega(-) decays are measured to be B Omega-->Xi 0 pi- = (25.03 +/- 0.44 +/- 0.53) %, B Omega-->Xi-pi 0 = (8.43 +/- 0.52 +/- 0.28) %, and B Omega-->Lambda K- = (66.3 +/- 0.8 +/- 2.0) %, where the first and second uncertainties are statistical and systematic, respectively. The ratio between B Omega-->Xi 0 pi- and B Omega-->Xi-pi 0 is determined to be 2.97 +/- 0.19 +/- 0.11, which is in good agreement with the PDG value of 2.74 +/- 0.15, but greater by more than four standard deviations than the theoretical prediction of 2 obtained from the Delta I = 1/2 rule.

摘要：
Using a sample of 4.3 x 105 eta' -> eta pi 0 pi 0 events selected from the ten billion J=psi event dataset collected with the BESIII detector, we study the decay eta' -> eta pi 0 pi 0 within the framework of nonrelativistic effective field theory. Evidence for a structure at pi+pi- mass threshold is observed in the invariant mass spectrum of pi 0 pi 0 with a statistical significance of around 3.5 sigma, which is consistent with the cusp effect as predicted by the nonrelativistic effective field theory. After introducing the amplitude for describing the cusp effect, the pi pi scattering length combination a0 - a2 is determined to be 0.226 10.060stat 10.013syst, which is in good agreement with theoretical calculation of 0.2644 10.0051.

摘要：
We search for an axion-like particle (ALP) a through the process psi (3686) ->pi+pi-J/psi, J/psi -> gamma a, a -> gamma gamma in a data sample of (2.71 + 0.01) x 109 psi (3686) events collected by the BESIII detector. No significant ALP signal is observed over the expected background, and the upper limits on the branching fraction of the decay J/psi -> gamma a and the ALP-photon coupling constant ga gamma gamma are set at 95% confidence level in the mass range of 0.165 < ma < 2.84 GeV/c2. The limits on B(J/psi -> gamma a) range from 8.3 x 10-8 to 1.8 x 10-6 over the search region, and the constraints on the ALP-photon coupling are the most stringent to date for 0.165 < ma < 1.468 GeV/c2.

摘要：
The cross sections of the e(+) e(-) -> phi eta' process at center-of-mass energies from 3.508 to 4.951 GeV are measured with high precision using 26.1 fb(-1) data collected with the BESIII detector operating at the BEPCII storage ring. The cross sections are of the order of a few picobarn and decrease as the center-of-mass energy increases as s(-n/2) with n = 4.35 +/- 0.14. This result is in agreement with the Nambu-Jona-Lasinio model prediction of n = 3.5 +/- 0.9. In addition, the charmless decay psi(3770) -> phi eta' is searched for by fitting the measured cross sections, yet no significant signal is observed. The upper limit of B(psi(3770) -> phi eta') at the 90% confidence level is determined to be 2.3 x 10(-5).

摘要：
Using a data sample of (1.0087 +/- 0.0044) x 10(10) J/psi events collected with the BESIII detector, the decays of J/psi -> gamma pi(0) (eta, eta ') -> gamma gamma gamma are studied. Newly measured branching fractions are B(J/psi -> gamma pi(0)) = (3.34 +/- 0.02 +/- 0.09) x 10(-5), B(J/psi -> gamma eta) = (1.096 +/- 0.001 +/- 0.019) x 10(-3), and B(J/psi -> gamma eta ') = (5.40 +/- 0.01 +/- 0.11) x 10(-3), where the first uncertainties are statistical and the second are systematic. These results are consistent with the world average values within two standard deviations. The ratio of partial widths Gamma(J/psi -> gamma eta ')/Gamma(J/psi -> gamma eta) is measured to be 4.93 +/- 0.13. The singlet-octet pseudoscalar mixing angle theta(P) is determined to be theta(P) = -(22.11 +/- 0.26)degrees or -(19.34 +/- 0.34)degrees with two different phenomenological models.

摘要：
Using data samples with an integrated luminosity of 5.85 fb^{-1} collected at center-of-mass energies from 4.61 to 4.95GeV with the BESIII detector operating at the BEPCII storage ring, we measure the cross section for the process e^{+}e^{-}→K^{+}K^{-}J/ψ. A new resonance with a mass of M=4708_{-15}^{+17}±21 MeV/c^{2} and a width of Γ=126_{-23}^{+27}±30 MeV is observed in the energy-dependent line shape of the e^{+}e^{-}→K^{+}K^{-}J/ψ cross section with a significance over 5σ. The K^{+}J/ψ system is also investigated to search for charged charmoniumlike states, but no significant Z_{cs}^{+} states are observed. Upper limits on the Born cross sections for e^{+}e^{-}→K^{-}Z_{cs}(3985)^{+}/K^{-}Z_{cs}(4000)^{+}+c.c. with Z_{cs}(3985)^{±}/Z_{cs}(4000)^{±}→K^{±}J/ψ are reported at 90% confidence levels. The ratio of branching fractions {[B(Z_{cs}(3985)^{+}→K^{+}J/ψ)]/B[Z_{cs}(3985)^{+}→(D[over ¯]^{0}D_{s}^{*+}+D[over ¯]^{*0}D_{s}^{+})]} is measured to be less than 0.03 at 90% confidence level.

摘要：
We report on the first search for Lambda -Lambda oscillations in the decay J=psi -> pK- Lambda & thorn; c:c: by analyzing 1.31 x 10(9) J=psi events accumulated with the BESIII detector at the BEPCII collider. The J=psi events are produced using e(+) e(-) collisions at a center of mass energy root s= 3.097 GeV. No evidence for hyperon oscillations is observed. The upper limit for the oscillation rate of Lambda to Lambda hyperons is determined to be P(Lambda)=[B(J/psi -> pK(-)Lambda + c:c.)/B(J/psi -> pK(- )Lambda & thorn; c:c.)] < 4.4 x 10(-6) corresponding to an oscillation parameter delta m(Lambda Lambda ) of less than 3.8 x 10(-18 )GeV at the 90% confidence level.

摘要：
Based on 4.5 fb−1 data taken at seven center-of-mass energies ranging from 4.600 to 4.699 GeV with the BESIII detector at the BEPCII collider, we measure the branching fractions of
$$ {\Lambda}_c^{+} $$
→ Σ+ + hadrons relative to
$$ {\Lambda}_c^{+} $$
→ Σ+π+π−. Combining with the world average branching fraction of
$$ {\Lambda}_c^{+} $$
→ Σ+π+π−, their branching fractions are measured to be (0.377 ± 0.042 ± 0.020 ± 0.021)% for
$$ {\Lambda}_c^{+} $$
→ Σ+K+K−, (0.200 ± 0.023 ± 0.011 ± 0.011)% for
$$ {\Lambda}_c^{+} $$
→ Σ+K+π−, (0.414 ± 0.080 ± 0.030 ± 0.023)% for
$$ {\Lambda}_c^{+} $$
→ Σ+ϕ and (0.197 ± 0.036 ± 0.009 ± 0.011)% for
$$ {\Lambda}_c^{+} $$
→ Σ+K+K−(non-ϕ). In all the above results, the first uncertainties are statistical, the second are systematic and the third are from external input of the branching fraction of
$$ {\Lambda}_c^{+} $$
→ Σ+π+π−. Since no signal for
$$ {\Lambda}_c^{+} $$
→ Σ+K+π−π0 is observed, the upper limit of its branching fraction is determined to be 0.13% at the 90% confidence level.

摘要：
The processes e+e- - Delta++ Delta over bar -- and e+e- - Delta++ p over bar x-- + c:c: are studied for the first time with 179 pb-1 of e+e- annihilation data collected with the BESIII detector at center-of-mass energies from 2.3094 to 2.6464 GeV. No significant signal for the e+e- - Delta++ Delta over bar -- process is observed and the upper limit of the Born cross section is estimated at each energy point. For the process e+e- - Delta++ p over bar x-- + c:c:, a significant signal is observed at center-of-mass energies near 2.6454 GeV and the corresponding Born cross section is reported.

摘要：
Using a data sample of (1.0087 +/- 0.0044) x 10(10) J/psi decay events collected with the BESIII detector at the center-of-mass energy of root s = 3.097 GeV, we present a search for the hyperon semileptonic decay Xi(0) -> Sigma(-)e(+)nu(e) which violates the Delta S = Delta Q rule. No significant signal is observed, and the upper limit on the branching fraction B(Xi(0) -> Sigma(-)e(+)nu(e)) is determined to be 1.6 x 10(-4) at the 90% confidence level. This result improves the previous upper limit result by about one order of magnitude.

摘要：
The Cabibbo-allowed weak radiative decay A+c -> E+gamma has been searched for in a sample of A+c over bar A- c pairs produced in e+e- annihilations, corresponding to an integrated luminosity of 4.5 fb-1 collected with the BESIII detector at center-of-mass energies between 4.60 and 4.70 GeV. No excess of signal above background is observed, and we set an upper limit on the branching fraction of this decay to be B(A+c -> E+gamma) < 4.4 x 10-4 at a confidence level of 90%, which is in agreement with Standard Model expectations.

摘要：
We study the process e^{+}e^{-}→Λ_{c}^{+}Λ[over ¯]_{c}^{-} at twelve center-of-mass energies from 4.6119 to 4.9509GeV using data samples collected by the BESIII detector at the BEPCII collider. The Born cross sections and effective form factors (|G_{eff}|) are determined with unprecedented precision after combining the single and double-tag methods based on the decay process Λ_{c}^{+}→pK^{-}π^{+}. Flat cross sections around 4.63GeV are obtained and no indication of the resonant structure Y(4630), as reported by Belle, is found. In addition, no oscillatory behavior is discerned in the |G_{eff}| energy dependence of Λ_{c}^{+}, in contrast to what is seen for the proton and neutron cases. Analyzing the cross section together with the polar-angle distribution of the Λ_{c}^{+} baryon at each energy point, the moduli of electric and magnetic form factors (|G_{E}| and |G_{M}|) are extracted and separated. For the first time, the energy dependence of the form factor ratio |G_{E}/G_{M}| is observed, which can be well described by an oscillatory function.

摘要：
Based on (2712.4 +/- 14.3) x 106 events recorded at the psi(3686) nominal mass collected with the BESIII detector operating at the BEPCII collider, the psi(3686) -> E +/- E over bar -omega and E +/- E over bar -phi decays are observed for the first time with statistical significances of 13.8 sigma and 7.6 sigma, respectively. The corresponding branching fractions are measured to be B(psi (3686) -> E +/- E over bar -omega) = (1.89 +/- 0.18 +/- 0.21) x 10-5 and B(psi (3686) -> E +/- E over bar -phi) = (2.96 +/- 0.54 +/- 0.41) x 10-6, where the first uncertainties are statistical and the second systematic.

摘要：
Using initial-state radiation events from a total integrated luminosity of 11.957 fb-1 of e thorn e- collision data collected at center-of-mass energies between 3.773 and 4.258 GeV with the BESIII detector at BEPCII, the cross section for the process e thorn e- -> AA over bar is measured in 16 AA over bar invariant mass intervals from the production threshold up to 3.00 GeV=c2. The results are consistent with previous results from BABAR and BESIII, but with better precision and with narrower AA over bar invariant mass intervals than BABAR.

摘要：
Calreticulin (CRT) is a multifunctional protein found within the endoplasmic reticulum (ER). In addition, CRT participates in the formation and development of tumors and promotes the proliferation and migration of tumor cells. When a malignant tumor occurs in the human body, cancer cells that die from immunogenic cell death (ICD) expose CRT on their surface, and CRT that is transferred to the cell surface represents an "eat me" signal, which promotes dendritic cells to phagocytose the tumor cells, thereby increasing the sensitivity of tumors to anticancer immunotherapy. Expression of CRT in tumor tissues is higher than in normal tissues and is associated with disease progression in many malignant tumors. Thus, the dysfunctional production of CRT can promote tumorigenesis because it disturbs not only the balance of healthy cells but also the body's immune surveillance. CRT may be a diagnostic marker and a therapeutic target for cancer, which is discussed extensively in this review.

摘要：
Using 15. 6 fb(-1) of e(+)e(-) collision data collected at twenty-four center-of-mass energies from 4. 0 to 4.6 GeV with the BESIII detector, the helicity amplitudes of the process e(+)e(-) -> pi(+)pi(-)omega are analyzed for the first time. Born cross section measurements of two-body intermediate resonance states with statistical significance greater than 5 sigma are presented, such as f(0)(500), f(0)(980), f(2)(1270), f(0)(1370), b(1)(1235)(+/-), and rho(1450)(+/-). In addition, evidence of a resonance state in e(+)e(-) -> pi(+)pi(-)omega production is found. The mass of this state obtained by line shape fitting is about 4.2 GeV/c(2), which is consistent with the production of psi(4160) or Y (4220).
