A suggested search for doubly charmed baryons of $J^P=3/2^+$ via their electromagnetic transitions

TL;DR

This paper employs light-cone sum rules to estimate the electromagnetic decay width of the doubly charmed baryon $ ext{Xi}^{*++}_{cc}$, suggesting it could be observed in future collider experiments.

Contribution

It provides a theoretical estimate of the electromagnetic decay width of the doubly charmed baryon $ ext{Xi}^{*++}_{cc}$ using light-cone sum rules, guiding experimental searches.

Findings

Decay width estimated at approximately 13.7 keV

Decay width is large enough for experimental detection

Proposes search in LHCb and BelleII experiments

Abstract

We use the method of light-cone sum rules to study the electromagnetic transition of the $\Xi^{*++}_{cc}$ into $\Xi^{++}_{cc}\gamma$, whose decay width is estimated to be $13.7~{^{+17.7}_{-~7.9}}$ keV. This value is large enough for the $\Xi^{*++}_{cc}$ to be observed in the $\Xi^{++}_{cc}\gamma$ channel, and we propose to continually search for it in future LHCb and BelleII experiments.
