$Λ_{b} \to Λ ℓ^{+} ℓ^{-}$ and $Λ_{b} \to Λ^{*} ℓ^{+} ℓ^{-}$ decays with polarized leptons

Diganta Das, Vedant Parekh, Ria Sain +1

We present an analysis of lepton polarization observables in the rare flavor-changing neutral current decays $Λ_{b} \to Λ ℓ^{+} ℓ^{-}$ and $Λ_{b} \to Λ^{*} ℓ^{+} ℓ^{-}$ . These decays are…

Probing Light Dark Fermions in $B \to D^{(*)} ℓ X_{inv}$ via Rate Distributions

Lipika Kolay, Soumitra Nandi, Shantanu Sahoo +1

Experimental analyses of the semileptonic decays $B \to D^{(*)} ℓ ν ˉ$ typically rely on the assumption that the missing energy originates from a massless neutrino, as predic…

$∣ V_{c b} ∣$ determinations from $B ˉ \to D^{(*)} ℓ ν ˉ$ decays within the SM and beyond

Wen-Sheng Fang, Syuhei Iguro, Xin-Qiang Li +3

We investigate the $∣ V_{c b} ∣$ determinations from exclusive semi-leptonic $B ˉ \to D^{(*)} ℓ ν ˉ$ decays, together with comprehensive Bayesian fit analyses of the $\bar{B} \…
