dc.description.abstractA partial wave analysis on the process e(+)e(-) -> omega(+)pi(-) is performed using 647 pb(-1) of data sample collected by using the BESIII detector operating at the BEPCII storage ring at center-of-mass (c.m.) energies from 2.000 GeV to 3.080 GeV. The Born cross section of the e(+)e(-) -> omega pi(+)pi(-) process is measured, with precision improved by a factor of 3 compared to that of previous studies. A structure near 2.25 GeV is observed in the energy-dependent cross sections of e(+)e(-) -> omega pi(+)pi(-) and omega pi(0)pi(0) with a statistical significance of 7.6 sigma, and its determined mass and width are 2232 +/- 19 +/- 27 MeV/c(2) and 93 +/- 53 +/- 20 MeV, respectively, where the first and second uncertainties are statistical and systematic, respectively. By analyzing the cross sections of subprocesses e(+)e(-) -> omega f(0)(500), omega f(0)(980), omega f(0)(1370), omega f(2)(1270), and b(1)(1235)pi, a structure, with mass M = 2200 +/- 11 +/- 17 MeV/c(2) and width Gamma = 74 +/- 20 +/- 24 MeV, is observed with a combined statistical significance of 7.9 sigma. The measured resonance parameters will help to reveal the nature of vector states around 2.25 GeV.en_US
