Productions of $D_{s0}^{\ast }(2317)$ and $D_{s1}(2460)$ in $B_{(s)}$ and ${\Lambda }_b({\Xi }_b)$ decays

Abstract

Recent studies show that $D_{s0}^{\ast }(2317)$ and $D_{s1}(2460)$ contain large molecular components. In this work, we employ the naive factorization approach to calculate the production rates of $D_{s0}^{\ast }(2317)$ and $D_{s1}(2460)$ as hadronic molecules in $B_{(s)}$ and ${\Lambda }_b({\Xi }_b)$ decays, where their decay constants are estimated in the effective Lagrangian approach. With the so-obtained decay constants $f_{D_{s0}^{\ast }(2317)}$ and $f_{D_{s1}(2460)}$, we calculate the branching fractions of the $b$-meson decays $B_{(s)}\to {\bar{D}}_{(s)}^{(\ast )}{D}_{s0}^{\ast }$ and $B_{(s)}\to {\bar{D}}_{(s)}^{(\ast )}{D}_{s1}$ and the $b$-baryon decays ${\Lambda }_b({\Xi }_b)\to {\Lambda }_c({\Xi }_c)D_{s0}^{\ast }$ and ${\Lambda }_b({\Xi }_b)\to {\Lambda }_c({\Xi }_c)D_{s1}$. Our results show that the production rates of $D_{s0}^{\ast }(2317)$ and $D_{s1}(2460)$ in the $B_s$, ${\Lambda }_b$ and ${\Xi }_b$ decays are rather large that future experiments could observe them. In particular, we demonstrate that one can extract the decay constants of hadronic molecules via the triangle mechanism because of the equivalence of the triangle mechanism to the tree diagram established in calculating the decays $B\to {\bar{D}}^{(\ast )}{D}_{s0}^{\ast }(2317)$ and $B\to {\bar{D}}^{(\ast )}{D}_{s1}(2460)$.
