Inspection of new physics in ${\mathrm{B}}_{\mathrm{s}}^0\to {\mathrm{K}}^{+}{\mathrm{K}}^{-}$ decay mode

Manas K. Mohapatra

We scrutinize the penguin dominated $B_s\to K^{+}{K}^{-}$ decay mode involving $b\to s$ quark level transition in family non-universal $Z^{\prime }$ and vector-like down quark model. T…
