Production of the $X_b$ in ${\rm Y}(5S,6S)\to \gamma X_b$ radiative decays

Qi Wu, Gang Li, Fenglan Shao +4

In this work, we investigate the production of $X_b$ in the process ${\rm Y}(5S,6S)\to \gamma X_b$, where $X_b$ is assumed to be the counterpart of $X(3872)$ in the bottomonium sector as a $B…
