Consequences of $b \to s μ^{+} μ^{-}$ anomalies on $B \to K^{(*)} ν ν ˉ$ , $B_{s} \to (η, η^{'}) ν ν ˉ$ and $B_{s} \to ϕ ν ν ˉ$ decay observables

N Rajeev, Rupak Dutta

The long persistent discrepancies in $b \to s ℓ ℓ$ quark level transitions continue to be the ideal platform for an indirect search of new physics that lies beyond the…

New physics footprints in the angular distribution of $B_{s} \to D_{s}^{*} (\to D_{s} γ, D_{s} π) τ ν$ decays

Nilakshi Das, Rupak Dutta

Hints of lepton flavor universality violation observed in various flavor ratios such as $R_{D}$ , $R_{D^{*}}$ , $R_{J / ψ}$ , $P_{τ}^{D^{*}}$ and $F_{L}^{D^{*}}$ in $B \to D^{(*)} ℓ ν$ and $B…

Combined analysis of $B_{c} \to D_{s}^{()} μ^{+} μ^{-}$ and $B_{c} \to D_{s}^{()} ν ν ˉ$ decays within $Z^{'}$ and leptoquark new physics models

Manas K. Mohapatra, N Rajeev, Rupak Dutta

We investigate the exclusive rare semileptonic decays $B_{c} \to D_{s}^{(*)} (ℓℓ, ν ν ˉ)$ induced by neutral current transition $b \to s (ℓℓ, ν ν ˉ)$ in the presence…
