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…

Status of G2HDM with right handed neutrino coupling in the light of $b \to c τ ν$ anomalies

Nilakshi Das, Amit Adhikary, Rupak Dutta

Recent experimental measurements of several observables in semileptonic B meson decays have pointed towards the possibility of new physics. The LHCb collaboration has reported a si…

One vanishing minor in neutrino mass matrix using trimaximal mixing

Iffat Ara Mazumder, Rupak Dutta

We investigate the implications of one vanishing minor in neutrino mass matrix using trimaximal mixing matrix. In this context, we analyse all six patterns of one vanishing minor z…

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…
