Production of the (predicted) $K^{\ast }(4307)$ in $B$ decays

Xiu-Lei Ren, K. P. Khemchandani, A. Martinez Torres

In this work we study the production of $K^{\ast }(4307)$ in $B$ decays by determining the $J/\psi {\pi }^{+(0)}{K}^0$ and $J/\psi {\pi }^{-}{K}^{+}$ invariant mass distributions of the processes $B^+\to J/ψπ^…
