Abstract

Semileptonic decays of the $B \overline{B}$ pairs produced in the $\mathit{\Upsilon}(5S)$ can be used to find the relative probability of $\mathit{\Upsilon}(5S) \rightarrow B_s \overline{B}_s$ decays. This could be achieved by the study of time dependence of $B$-meson decays to the leptons of equal and opposite signs.
