Determine the mass and experimental visibility of the missing Omega_b 3/2-minus state

Determine the precise mass and experimental visibility of the missing [Omega_b(3/2^-),1,1,lambda] configuration, which is predicted to lie near the observed Omega_b(6316) structure.

Background

The paper classifies the P-wave flavor-sextet Omega_b states into HQET multiplets and proposes assignments for the observed Omega_b(6316), Omega_b(6330), Omega_b(6340), and Omega_b(6350) structures. Within this interpretation, the JP=3/2- partner of the state associated with Omega_b(6316) is not experimentally resolved. The authors suggest that it may lie close to Omega_b(6316), but explicitly state that its mass and visibility remain uncertain, leaving its experimental identification unresolved.

References

The missing $[\Omega_b(3/2-),1,1,\lambda]$ configuration may lie in the vicinity of $\Omega_b(6316)$, although its precise mass and experimental visibility remain uncertain.
