Evidence for a parity doublet Delta(1920)Rho33 and Delta(1940)Delta33 from gamma-rho -> rho-pi0eta
Abstract
Evidence is reported for the existence of a parity doublet of Delta resonances with total angular momentum J =3/2 from photoproduction of the rho-pi0eta final state. The two parity partners Delta(1920)Rho33 and Delta(1940)Delta33 make significant contributions to the reaction. Cascades of resonances into Delta(1232)eta, Ni(1535)pi, and Na0(980) are clearly observed.
