Year: 2025

Type: article

Abstract: Semileptonic decays of the $$B \overline{B}$$ B B ¯ pairs produced in the $${\varUpsilon }(5S)$$ Υ ( 5 S ) can be used to find the relative probability of $${\varUpsilon }(5\,S) \rightarrow B_s \overline{B}_s$$ Υ ( 5 S ) → B s 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.
