Neutrino mass variables in 3 active and 2 sterile neutrino scenario

Srubabati Goswami, Hemanth M., Debashis Pachhar +1

The three-flavor framework of neutrino oscillations successfully explains most experimental results, but persistent anomalies at short- and long-baseline experiments hint at the ex…

Constraints on lepton flavor universal and non-universal New Physics in $b \to s ℓ^{+} ℓ^{-}$ decays: a global SMEFT survey

Md Isha Ali, Utpal Chattopadhyay, Dilip Kumar Ghosh +1

The flavor-changing neutral current semileptonic decays of $B$ mesons provide an excellent platform for indirectly probing New Physics (NP) beyond the Standard Model (SM). Recent m…

Angular analysis of $B_{s} \to f_{2}^{'} (1525) (\to K^{+} K^{-}) μ^{+} μ^{-}$ decays as a probe to lepton flavor universality violation

N Rajeev, Niladribihari Sahoo, Rupak Dutta

The flavor anomalies reported in $R_{K}$ , $R_{K^{*}}$ , $P_{5}^{'}$ and $B (B_{s} \to ϕ μ^{+} μ^{-})$ indicate lepton flavor universality violation in $b \to s\,l^+\,l^-…

Probing new physics in $B_{s} \to (K, K^{*}) τ ν$ and $B \to π τ ν$ decays

N Rajeev, Rupak Dutta

Motivated by the anomalies present in $b \to u$ and $b \to c$ semileptonic decays, we study the corresponding $B_{s} \to (K, K^{*}) τ ν$ and $B \to π τ ν$ decays within an effective field…

Signature of lepton flavor universality violation in $B_{s} \to D_{s} τ ν$ semileptonic decays

Rupak Dutta, N Rajeev

Deviation from the standard model prediction is observed in many semileptonic $B$ decays mediated via $b \to c$ charged current interactions. In particular, current experimental me…
