英文摘要 | In this paper we perform an amplitude analysis of eta ' -> pi(+)pi(-)gamma and confront it with the latest besiii data. based on the final-state interaction theorem, we represent the amplitude in terms of an omnes function multiplied by a form factor that corresponds to the contributions from left-hand cuts and right-hand cuts in the inelastic channels. we also take into account the isospin violation effect induced by rho-omega mixing. our results show that the anomaly contribution is mandatory in order to explain the data. its contribution to the decay width of gamma(eta ' -> pi pi gamma) is larger than that induced by isospin violation. finally we extract the pole positions of the rho and omega as well as their corresponding residues. |
