$B$ and $B_s$ Meson Spectroscopy

Abstract

Properties of bottom and bottom-strange mesons are computed in two relativized quark models. Model masses and wavefunctions are used to predict radiative transition rates and the ${}^3{P}_0$ quark pair creation model is used to compute strong decay widths. A comparison to recently observed bottom and bottom-strange states is made. We find that there are numerous excited $B$ and $B_s$ mesons that have relatively narrow widths and significant branching ratios to simple final states such as $B\pi$, $B^{\ast }\pi$, $BK$, and $B^{\ast }K$ that could be observed in the near future.
