New physics in $b \to s e^{+} e^{-}$ : A model independent analysis

Ashutosh Kumar Alok, Suman Kumbhakar, Jyoti Saini +1

The lepton universality violating flavor ratios $R_{K} / R_{K^{*}}$ indicate new physics either in $b \to s μ^{+} μ^{-}$ or in $b \to s e^{+} e^{-}$ or in both. If the new physics is only $b \to…

Probing signatures of beyond standard model physics through $B_{s}^{*} \to μ^{+} μ^{-}$ decay

Jyoti Saini, Dinesh Kumar, Shireen Gangal +1

We perform a model independent analysis to identify new physics operators which can enhance the branching ratio of $B_{s}^{*} \to μ^{+} μ^{-}$ above its Standard Model (SM) predict…

Flavor signatures of complex anomalous $t c Z$ couplings

Suman Kumbhakar, Jyoti Saini

In this work we study the effects of anomalous $t c Z$ couplings. Such couplings would potentially affect several neutral current decays of $K$ and $B$ mesons via $Z$ -penguin diagram…

New physics effects in purely leptonic $B_{s}^{*}$ decays

Suman Kumbhakar, Jyoti Saini

Recently several measurements in the neutral current sector $b \to s l^{+} l^{-}$ ( $l = e$ or $μ$ ) as well as in the charged current sector $b \to c τ ν ˉ$ show significan…
