Lepton polarization dependent angular observables and the polarization asymmetries in the four-fold decay

Rana Khan, Faisal Munir Bhutta, Ishtiaq Ahmed +1

The rare decays mediated by flavor-changing neutral current processes, such as , provide powerful probes of the Standard Model and potential windows into…

Weak decay of the positronium ion

Nishat Ul Sani, M. Jamil Aslam, Ishtiaq Ahmed

The positronium ion (), 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 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 -meson decays. Exploiting these relations,…

The Angular Observables of within the Paradigm of FCCC Anomalies

Muhammad Arslan, Ishtiaq Ahmed, Muhammad Jamil Aslam

We present a global analysis of the current -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)…

Addressing the puzzle through New Physics four-fermion operators and their impact on decay

Muhammad Arslan, Ishtiaq Ahmed, Muhammad Jamil Aslam +2

The Lepton Flavor Universality ratio poses a challenge to the Standard Model (SM), as B-factory experiments, BaBar, Belle, and the LHCb show $3.…

Radiative B to tensor meson decays at NLO in SCET

Arslan Sikandar, M. Jamil Aslam

The radiative to tensor meson decays are studied at next-to-leading order (NLO) in soft-collinear effective theory (SCET).…
