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…

Exploring new physics in the FCNC $B_{c} \to D_{s} ν ν ˉ$ channel

Tarun Kumar, Barilang Mawlong

The rare $b \to s ℓ^{+} ℓ^{-}$ transition is a well-explored transition, particularly for new physics beyond the standard model. Similar to this transition, another flavor changin…
