Mass spectra and decay properties of singly heavy bottom-strange baryons

Abstract

In this paper, we enumerated ground and excited state masses of singly heavy bottom-strange baryons using the hypercentral constituent quark model (hCQM). The screening potential is used with color-Coulomb potential, as the confining potential. We determine the possible [Formula: see text] values to recently observed excited states like, [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] and four [Formula: see text] states. The Regge trajectories are plotted in [Formula: see text] plane to assign the [Formula: see text] values and quantum numbers to recently observed states. Using the calculated spectroscopic data, properties such as magnetic moment, transition magnetic moment, radiative decay width, and strong decay width are also investigated for all singly heavy bottom-strange baryonic system.

An updated review of the new hadron states

“…The four peaks observed by LHCb are consistent with the expectations for the excited Ω b resonances. However, there do exist many possible interpretations for them [289][290][291][292][293][294], since there can be as many as five λ-mode and two ρ-mode Ω b (1P) states, as shown in figure 6. We briefly review two possible explanations as follows.…”

Spectra of triply heavy Ωccb and Ωbbc baryons

“…The hypercentral potential is used with a non relaticistic approach. We consider V(x) as [35][36][37][38][39][40][41],…”

“…In this paper, we determine the mass spectra of triply charm bottom Ω ccb and Ω bbc baryons in the framework of the Hypercentral constituent quark model with screened potential. Previously the same methodology has been used to determine the masses of singly charm [35,36], singly bottom [37,38], doubly heavy baryons [39,40] and triply charm and triply bottom baryons [41]. The model has successfully determined the unknown quantum numbers of baryonic states.…”
