Polarized and un-polarized $R_{K^{*}}$ in and beyond the SM

Ishtiaq Ahmed, Saba Shafaq, M. Jamil Aslam +1

The Standard Model (SM) is lepton flavor universal, and the recent measurements of lepton flavor universality in $B \to (K, K^{*}) ℓ^{+} ℓ^{-}$ , for $ℓ = I^¼, e$ , decays now…

Angular observables of the four-fold $B \to K_{1} (1270, 1400) (\to V P) ℓ^{+} ℓ^{-}$ decays in and beyond the Standard Model

Faisal Munir Bhutta, Abdur Rehman, M. Jamil Aslam +2

Recent measurements of the lepton flavor universality ratios $R_{K}^{I^¼ e}$ and $R_{K^{*}}^{I^¼ e}$ in $B \to (K, K^{*}) I^¼^{+} I^¼^{-} (e^{+} e^{-})$ at LHCb align with the S…

Semileptonic $W$ Decay to the $B$ Meson with Lepton Pairs in Heavy Quark Effective Theory Factorization upto $O$ $(I^\pm_{s})$

Saadi Ishaq, Sajawal Zafar, Abdur Rehman +1

Motivated by the study of heavy-light meson production within the framework of heavy quark effective theory (HQET) factorization, we extend the factorization formalism for a rather…
