Electromagnetic and weak decays of baryons in the unquenched quark model

TL;DR

This paper investigates baryon electromagnetic and weak decays using an unquenched quark model, demonstrating that sea quark effects help explain discrepancies with experimental data and analyzing flavor-symmetry breaking.

Contribution

It introduces an unquenched quark model approach to baryon decays, highlighting the role of sea quarks in resolving previous model-data discrepancies.

Findings

Sea quark effects significantly improve decay predictions.

Discrepancies with experimental data are largely explained by the model.

Flavor-symmetry breaking impacts decay processes.

Abstract

In this contribution, we discuss the electromagnetic and weak decays of baryons in the unquenched quark model and show that the observed discrepancies between the experimental data and the predictions of the constituent quark model can be accounted for in large part by the effects of sea quarks. Finally, the obtained results are discussed in terms of flavor-symmetry breaking.
