Lepton polarization dependent angular observables and the polarization asymmetries in the four-fold $I^_{b} \to I^ (\to N I ¨ ) ℓ^{+} ℓ^{-}$ decay

Rana Khan, Faisal Munir Bhutta, Ishtiaq Ahmed +1

The rare decays mediated by flavor-changing neutral current processes, such as $b \to s ℓ^{+} ℓ^{-}$ , provide powerful probes of the Standard Model and potential windows into…

A Phenomenological Study of Semileptonic $B^{+}$ and $B_{s}^{0}$ Decays into Axial-Vector Mesons $(D_{1} (2420), D_{1}^{'} (2430), D_{s 1} (2460), and D_{s 1}^{'} (2536))$ within the Standard Model

Rana Khan, Qazi Maaz Us Salam, Zohaib Aarfi +1

We study semileptonic $B$ meson decays $B^{+} \to D_{1}^{(')} ℓ^{+} I^½_{ℓ}$ and $B_{s}^{0} \to D_{s 1}^{- (')} ℓ^{+} I^½_{ℓ}$ , where $ℓ = I^¼, I ¨ $ . The final state axial vector meson…

Chirality structure of vector like new physics operators in charged current transitions

Sajawal Zafar, Qazi Maaz Us Salam, Rana Khan +2

We investigate the cascade decay $B_{s}^{* 0} \to D_{s}^{-} (\to I ¨ ^{-} I^ˉ ½_{I ¨} ) ℓ^{+} I^½_{ℓ}$ induced by flavor changing charged currents in the context of the St…
