New physics analysis of $Λ_{b} \to (Λ^{*} (\to p K^{-}), Λ (\to p π)) (μ^{+} μ^{-}, ν ν ˉ)$ baryonic decays under SMEFT framework

Nilakshi Das, Rupak Dutta

The di-leptons and di-neutrinos observed in the final states of flavor-changing neutral b decays provide an ideal platform for probing physics beyond the standard model. Although t…

Implication of $b \to c τ ν$ flavor anomalies on $B_{s} \to D_{s}^{*} τ ν$ decay observables

Nilakshi Das, Rupak Dutta

The experimental predictions of $R_{D}$ , $R_{D^{*}}$ , $R_{J / ψ}$ , $P_{τ}^{D^{*}}$ and $F_{L}^{D^{*}}$ in $B$ decays mediated via $b \to c l ν$ quark level transition deviate significantly…
