A Comprehensive Analysis of $B_{s} \to D_{s}^{**} ℓ ν_{ℓ}$ Decays Within and Beyond the Standard Model

Karthik Jain, Tarun Kumar, Barilang Mawlong +1

We examine the exclusive semileptonic decays $B_{s} \to D_{s}^{**} ℓ ν_{ℓ}$ , with $D_{s}^{**} =$ ${D_{s 0}^{*}, D_{s 1}^{*}, D_{s 1}, D_{s 2}^{*}}$ , within the Standard Model and beyo…

Probing the $Λ_{b} \to Λ_{c}^{*} τ ν ˉ_{τ}$ decays with leptoquarks

C P Haritha, Karthik Jain, Barilang Mawlong

The extension of the standard model to include a single scalar or vector leptoquark has been shown to account for the observed deviations in the lepton flavor universality ratios i…

Exploring New Physics in $D_{(s)}^{+} \to η^{(')} ℓ ˉ ν_{ℓ}$ Decays

Karthik Jain, Barilang Mawlong

The observation of anomalies in the charged current $b \to c ℓ ˉ ν_{ℓ}$ transitions hints the possibility of the existence of new physics beyond the standard model.…
