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 $P_{1} P_{2} = D^{+} π^{0}$ or $D^{0} π^{+}$ , and $ℓ = μ, τ$ . We focus on the impact of weak…

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

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

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

Reinvestigating the semileptonic $B \to D^{(*)} τ ν ˉ_{τ}$ 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 $B \to D^{(*)} τ ν ˉ_{τ}$ decays. To explore the structure of new phys…

Effects of Family Non-universal $Z^{'}$ Model in the angular observables of $B \to (ρ, a_{1}) μ^{+} μ^{-}$ decays

Nimra Farooq, Marwah Zaki, M. Ali Paracha +1

We present the angular distribution of the four-fold $B \to ρ (\to π π) μ^{+} μ^{-}$ and $B \to a_{1} (\to ρ_{∥, ⊥} π) μ^{+} μ^{-}$ decays both in the Standard Model and the family…

Footprints of New Physics in the angular distribution of $B_{c} \to D_{s}^{*} (\to D_{s} γ, (D_{s} π)) ℓ^{+} ℓ^{-}$ decays

Marwah Zaki, M. Ali Paracha, Faisal Munir Bhutta

We investigate the angular decay distribution of the four-fold $B_{c} \to D_{s}^{*} (\to D_{s} γ) μ^{+} μ^{-}$ , and $B_{c} \to D_{s}^{*} (\to D_{s} π) μ^{+} μ^{-}$ decays that proceed…
