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 $R_{K}^{μ e}$ and $R_{K^{*}}^{μ e}$ in $B \to (K, K^{*}) μ^{+} μ^{-} (e^{+} e^{-})$ at LHCb align with the Stand…

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 $ℓ = μ, e$ , decays now l…

Radiative $B$ to axial-vector meson decays at NLO in Soft-Collinear Effective Theory

Arslan Sikandar, M. Jamil Aslam, Ishtiaq Ahmed +1

The rare decay $B \to A γ$ , with $A$ representing axial-vector mesons such as $K_{1} (1270), K_{1} (1400), b_{1} (1300), a_{1} (1260)$ , is studied at next-to-leading order (NLO)…

Interpretation of LHCb Hidden-Charm Pentaquarks within the Compact Diquark Model

Ahmed Ali, Ishtiaq Ahmed, M. Jamil Aslam +2

The LHCb collaboration have recently updated their analysis of the resonant $J / ψ p$ mass spectrum in the decay $Λ_{b}^{0} \to J / ψ p K^{-}$ , making use of their combined Run~1 and R…

Probing new physics effects in $Λ_{b} \to Λ (\to p π^{-}) ℓ^{+} ℓ^{-}$ decay via model independent approach

Aqsa Nasrullah, Ishtiaq Ahmed, M. Jamil Aslam +2

The New Physics (NP) effects are studied in the rare baryonic decay $Λ_{b} \to Λ (\to p π^{-}) ℓ^{+} ℓ^{-}$ , with unpolarized $Λ_{b}$ using most general model independent approach by i…

Vertex renormalization and hard scattering symmetry breaking corrections to $B$ to axial vector meson form factors at large recoil

Arslan Sikandar, M. Jamil Aslam, Ishtiaq Ahmed +1

The symmetries arise due to heavy quark and large energy limit help us to reduce the number of independent form factors in the heavy-to-light $B$ -meson decays. It is expected that…
