M2 signatures in psi(2S) radiative decays

High Energy Physics - Phenomenology 2008-12-30 v2

Abstract

The sensitivity of observables in radiative decays psi(2S) -> gamma chi_{1,2} -> gamma gamma J/psi to quadrupole (M2) admixtures in the dominant electric dipole (E1) transitions is explored. Emphasis is placed on distributions in a single angle, and several examples are given.
