Search for New Physics through the Observables of Semileptonic $B_{c}^{+} \to D^{*+} ℓ^{+} ℓ^{-}$ Decay

Zohaib Aarfi, Qazi Maaz Us Salam, Faisal Munir Bhutta +2

Motivated by the current flavor anomalies and the comparatively less explored nature of the $b \to d$ sector, we present a model-independent study of the rare semileptonic $B_c^{+}\…

Weak Annihilation Contribution to Angular Observables in $B_{c}^{+} \to D^{*+} ℓ^{+} ℓ^{-}$ Decays

Zohaib Aarfi, Qazi Maaz Us Salam, Ishtiaq Ahmed +2

We analyze the rare semileptonic decays $B_{c}^{+} \to D^{*+} (\to P_{1} P_{2}) ℓ^{+} ℓ^{-}$ , with $P_{1} P_{2} = D^{+} I ¨ ^{0}$ or $D^{0} I ¨ ^{+}$ , and $ℓ = I^¼, I ¨ $ . We focus on the impact of…

Investigating New Physics through the Observables of Semileptonic $B_{s} \to K^{*} (\to K I ¨ ) I^¼^{+} I^¼^{-}$ Decay

Zohaib Aarfi, Qazi Maaz Us Salam, Ishtiaq Ahmed +3

The rare four-fold decay $B_{s} \to K^{*} (\to K I ¨ ) I^¼^{+} I^¼^{-}$ , governed by the flavor-changing neutral current transition $b \to d I^¼^{+} I^¼^{-}$ , provides a sensitive probe for testing the S…

Reinvestigating the semileptonic $B \to D^{(*)} I ¨ I^ˉ ½_{I ¨} $ decays in the model independent scenarios and leptoquark models

Zhuo-Ran Huang, Faisal Munir Bhutta, Nimra Farooq +2

In this work, we revisit the possible new physics (NP) solutions by analyzing the observables associated with $B \to D^{(*)} I ¨ I^ˉ ½_{I ¨} $ decays. To explore the structure of new p…
