Symmetry analysis of charmonium decays to two-baryon final state

High Energy Physics - Phenomenology 2022-03-14 v1

Abstract

By virtue of SU(3) flavor symmetry, the effective interaction Hamiltonian is derived in tensor form. The strong and electromagnetic breaking effects are taken into account in a form of "spurion" octet, so that the systematical parametrization of all baryon pair final states is realized on basis of the flavor-singlet principle. As an application, the relative phase between the strong and electromagnetic amplitudes is studied in the light of this scenario. In analyzing the data taken at J/ψ\psi resonance region in e+ee^+e^- collider, the details of experimental effects, such as energy spread and initial state radiative correction are taken into consideration in order to obtain the correct results.
