Measurement of the effective $B^0_s \rightarrow K^+ K^-$ lifetime
A precise determination of the effective $B^0_s \rightarrow K^+ K^-$ lifetime can be used to put constraints on new physics contributions in the $B_s^0$ meson system. Conventional approaches to select $B$ mesons and suppress combinatorial background rely on decay products which are significantly d...
