Hidden-bottom molecular states from ${\Sigma }_b^{(\ast )}{B}^{(\ast )}-{\Lambda }_b{B}^{(\ast )}$ interaction

In this work, we study possible hidden-bottom molecular pentaquarks $P_b$ from coupled-channel ${\Sigma }_b^{(\ast )}{B}^{(\ast )}-{\Lambda }_b{B}^{(\ast )}$ interaction in the quasipotential Bethe-Salpeter equati…
