Polarization in $Λ \to p μ^{-} ν ˉ_{μ}$ as a probe of CP-violating new physics

Qazi Maaz Us Salam, Ishtiaq Ahmed

We investigate the normal $μ$ polarization in the hyperon decay $Λ \to p μ^{-} ν ˉ_{μ}$ as a probe of new physics that violates CP, since this polarization vanishes at tree level in the…

Testing Minimal $U (2)^{3}$ Right-Handed Flavor Breaking in a Singlet-Scalar Vector-Like Quark Portal

Qazi Maaz Us Salam

We study a portal of a $Z_{2}$ -odd singlet scalar and a vector like down quark, in which a right handed flavor breaking spurion extends the portal coupling from $b_{R}$ to $d_{R}$ and $s…

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 $B^{+} \to D_{1}^{(')} ℓ^{+} ν_{ℓ}$ and $B_{s}^{0} \to D_{s 1}^{- (')} ℓ^{+} ν_{ℓ}$ , where $ℓ = μ, τ$ . The final state axial vector mesons ar…

Real and Complex Singlet-Scalar Benchmarks with a Vector-Like Down Quark for $B \to X_{s} γ$ and $B_{s} - B ˉ_{s}$ Mixing

Qazi Maaz Us Salam

We study a simple extension of the Standard Model with a vector-like down-type quark $D$ and a neutral singlet scalar $S = S_{R}, Φ$ . The scalar is considered in two forms, a rea…

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…

Exploring New Physics in transition $b \to s ℓ^{+} ℓ^{-}$ through different $B_{c} \to D_{s}^{(*)} ℓ^{+} ℓ^{-}$ observables

Qazi Maaz Us Salam, Ishtiaq Ahmed, Rizwan Khalid +1

Inspired by the discrepancies observed in the $b \to s ℓ^{+} ℓ^{-}$ neutral current decays, we study the decay channel $B_{c} \to D_{s}^{(*)} ℓ^{+} ℓ^{-}$ ( $ℓ = μ, τ$ ), which is ba…
