Jonathan L. Rosner
TL;DR
This paper investigates how M2 quadrupole admixtures affect observables in psi(2S) radiative decays, focusing on angular distributions to enhance understanding of transition dynamics.
Contribution
It introduces a detailed analysis of M2 contributions in psi(2S) radiative decays, emphasizing angular distribution sensitivities and providing examples for experimental exploration.
Findings
Angular distributions are sensitive to M2 admixtures.
Certain observables can distinguish E1 from M2 contributions.
The analysis guides future experimental measurements.
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.
