Abstract

In this work, we study the low-lying mass spectra for bottom-charmed baryons in a nonrelativistic quark model by solving the three-body Schr\"odinger equation. The lowest Ξbc\Xi_{bc}, Ξbc\Xi_{bc}^\prime, Ωbc\Omega_{bc}, and Ωbc\Omega_{bc}^\prime states are predicted to be about 6979, 6953, 7109, and 7092 MeV, respectively. Also, the strong decays for the low-lying excited states are investigated. Our results indicate that some of λ\lambda-mode PP-wave bottom-charmed baryons are relatively narrow, which can be searched for in future experiments. For the low-lying ρ\rho-mode and ρλ\rho-\lambda hybrid states, their strong decays are highly suppressed and they can survive as extremely narrow states. Moreover, the mass spectra and strong decays for bottom-charmed baryons preserve the heavy quark symmetry well. We hope our calculations can provide helpful information for further experimental and theoretical researches.
