Radiative decays of negative parity heavy baryons in QCD

TL;DR

This paper investigates the radiative decay processes of negative parity heavy baryons using light cone QCD sum rules, calculating transition form factors and decay widths to enhance understanding of these rare transitions.

Contribution

It introduces a novel application of light cone QCD sum rules to compute transition form factors and decay widths for specific negative parity heavy baryon radiative decays.

Findings

Calculated transition form factors for $ ext{Sigma}_Q o ext{Lambda}_Q ext{gamma}$ and $ ext{Xi}_Q' o ext{Xi} ext{gamma}$.

Determined decay widths for these radiative transitions.

Provided theoretical predictions for experimental comparison.

Abstract

The transition form factors responsible for the radiative $\Sigma_Q \to \Lambda_Q \gamma$ and $\Xi_Q^\prime \to \Xi \gamma$ decays of the negative parity baryons are examined within light cone QCD sum rules. The decay widths of the radiative transitions are calculated using the obtained results of the form factors.
