Possibility of the antibottom-strange molecular pentaquarks near $B\Sigma$ and $B^{\ast }\Sigma$ thresholds

Jian-Kang Zhao, Nijiati Yalikun

The molecular states in coupled channel system of $B_s^{0}N-B\Lambda -B^{\ast }\Lambda -B\Sigma -B^{\ast }\Sigma$ are investigated within one-boson-exchange model that includes $S$-$D$ wave mixing and a tunable shor…
