G. Lopez Castro, J. L. Lucio M., J. Pestieau
TL;DR
This paper analyzes J/psi decays using SU(3) flavor symmetry, considering both invariant and violating contributions, with focus on electromagnetic and strong amplitude interference.
Contribution
It introduces a comprehensive SU(3) symmetry analysis of J/psi decay modes, including symmetry-breaking effects and electromagnetic interference.
Findings
SU(3) symmetry provides a good description of decay patterns
Interference effects significantly influence decay amplitudes
Quantitative estimates of symmetry-violating contributions
Abstract
We use SU(3) flavor symmetry to analyze the and baryon-antibaryon decays of . Both, the SU(3)-invariant and -violating contributions are considered. Particular attention is paid to the interference of the electromagnetic and strong amplitudes.
