ϒ(5S)Mass ande+e−→BB―, BB―*, B*B―*as Sensitive Tests of the Unitarized Quark Model

Abstract

Because of hadronic mass shifts the $\Upsilon \mathrm{}\left(5S\right)-\Upsilon \mathrm{}\left(4S\right)\mathrm{}$ mass splitting is predicted to be 80 MeV larger than in naive potential models. The behavior of $\Delta R$ is predicted to show several bumps not corresponding to resonances.
