New results from VES
Abstract
The results of the patial wave analysis(PWA) of the pi+pi-pi- and omegapi-pi0 systems are presented. The a3 and a4(2040) signals are observed in the rho(770)pi and f2(1270)pi channels. Indications of the a1' meson existence was found in the 1+0+ rhopi S-wave. The decay branching ratio of the a2(1320)- to omegapi-pi0 was measured. The 2+1+ wave shows a broad bump at M~1.7GeV. The decays of the pi2(1670), a4(2040) and pi(1740) into omegarho- were found. The resonance in the b1(1235)pi wave with exotic quantum numbers jpc=1-+ at M~1.6 is observed and the simultaneous analysis of the 1-+ wave in the b1(1235)pi, etha'pi and rhopi final states is presented.
