Radiative M1 transitions of heavy baryons in the bag model

TL;DR

This paper investigates the magnetic dipole (M1) radiative transitions of heavy baryons using a modified bag model, calculating transition moments and decay widths while considering hyperfine mixing effects.

Contribution

It introduces a modified bag model approach to compute M1 transitions in heavy baryons, including hyperfine mixing effects, and compares results with other methods.

Findings

Transition moments and decay widths are calculated for heavy baryons.

Hyperfine mixing significantly affects the transition properties.

Results are consistent with or improve upon previous estimates.

Abstract

We study the M1 transitions of ground state heavy baryons within a framework of the modified bag model. Calculations of transition moments and corresponding M1 decay widths are performed. For the spin 1/2 baryons containing three differently flavoured quarks the hyperfine mixing effects are taken into account. Results are compared with estimates obtained using various other approaches.
