Newly Found Resonanceϒ(9.5)and the Charge of the Heavy Quark

Abstract

The newly discovered resonance $\Upsilon \mathrm{}\left(9.5\right)\mathrm{}$ is studied as a bound state of a heavy quark and its antiquark. From the estimate of the production cross section, it is argued that the charge of the constituent quark is likely to be $-\frac{1}{3}$.
