Improved $B \to K_{0}^{*} (1430)$ transition form factors at next-to-leading order in light cone sum rules

Arslan Sikandar, M. Jamil Aslam

We present an improved determination of the $B \to K_{0}^{*} (1430)$ transition form factors using light-cone sum rules (LCSR) with an expansion near the light cone. We include the one-l…

Weak decay of the positronium ion

Nishat Ul Sani, M. Jamil Aslam, Ishtiaq Ahmed

The positronium ion ( $Ps^{-}$ ), a coulombic three-body bound state of two electrons and a positron, predominantly decays via electron-positron annihilation into electromagne…

Symmetry-Breaking Effects on Form Factors and Observables in $B \to K_{0}^{*} (1430) μ^{+} μ^{-}$ Decay

Saba Ayub, Saba Shafaq, Arslan Sikandar +1

In the heavy-quark and large-energy limits, symmetry relations reduce the number of independent form factors governing heavy-to-light $B$ -meson decays. Exploiting these relations,…

The Angular Observables of $Λ_{b} \to Λ_{c} (\to Λ^{0} π^{+}) τ^{-} (\to π^{-} ν_{τ}) ν ˉ_{τ}$ within the Paradigm of FCCC Anomalies

Muhammad Arslan, Ishtiaq Ahmed, Muhammad Jamil Aslam

We present a global analysis of the current $B$ -meson flavor anomalies and extend it to the baryonic sector through the decay $Λ_{b}^{0} \to Λ_{c}^{+} (\to Λ^{0} π^{+}) τ^{-} (\to π^{-} ν_{τ}) ν ˉ_{τ}$ …

Addressing the $R_{τ / μ, e} (D^{(*)})$ puzzle through New Physics four-fermion operators and their impact on $Λ_{b} \to Λ_{c} τ ν ˉ_{τ}$ decay

Muhammad Arslan, Ishtiaq Ahmed, Muhammad Jamil Aslam +2

The Lepton Flavor Universality ratio $R_{τ / μ, e} (D^{(*)})$ poses a challenge to the Standard Model (SM), as B-factory experiments, BaBar, Belle, and the LHCb show $3.31…

Lepton polarization dependent angular observables and the polarization asymmetries in the four-fold $Λ_{b} \to Λ (\to N π) ℓ^{+} ℓ^{-}$ 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…
