摘要:
With the data samples taken at center-of-mass energies from 2.00 to 3.08 GeV with the BESIII detector at the BEPCII collider, a partial wave analysis on the e(+) e(-) -> pi(+) pi(-) pi(0) process is performed. The Born cross sections for e(+) e(-) -> pi(+) pi(-) pi(0) and its intermediate processes e(+) e(-) -> rho pi and rho(1450)pi are measured as functions of root s. The results for e(+) e(-) -> pi(+) pi(-) pi(0) are consistent with previous results measured with the initial state radiation method within one standard deviation, and improve the uncertainty by a factor of ten. By fitting the ...
