Molecular $\Omega_b$ states

TL;DR

This paper predicts new $ ext{Ω}_b$ molecular states in the beauty sector based on meson-baryon interactions, extending previous work on $ ext{Ω}_c$ states and identifying several potential states with specific quantum numbers and masses.

Contribution

It extends the meson-baryon interaction approach from the charm to the beauty sector, predicting multiple $ ext{Ω}_b$ states with specific quantum numbers and masses.

Findings

Predicted several $ ext{Ω}_b$ states with specific masses and quantum numbers.

Identified states with $J^P=\frac{1}{2}^-$ and $\frac{3}{2}^-$, including degenerate states.

Extended molecular state predictions from charm to beauty sector.

Abstract

Motivated by the recent finding of five $\Omega_c$ states by the LHCb collaboration, and the successful reproduction of three of them in a recent approach searching for molecular states of meson-baryon with the quantum numbers of $\Omega_c$, we extend these ideas and make predictions for the interaction of meson-baryon in the beauty sector, searching for poles in the scattering matrix that correspond to physical states. We find several $\Omega_b$ states: two states with masses 6405~MeV and 6465~MeV for $J^P= \frac{1}{2}^-$; two more states with masses 6427~MeV and 6665~MeV for $\frac{3}{2}^-$; and three states between 6500 and 6820~MeV, degenerate with $J^P=\frac{1}{2}^-,\,\frac{3}{2}^-$, stemming from the interaction of vector-baryon in the beauty sector.
