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…

Semileptonic $W$ Decay to the $B$ Meson with Lepton Pairs in Heavy Quark Effective Theory Factorization upto $O$ $(α_{s})$

Saadi Ishaq, Sajawal Zafar, Abdur Rehman +1

Motivated by the study of heavy-light meson production within the framework of heavy quark effective theory (HQET) factorization, we extend the factorization formalism for a rather…

$W$ radiative decay to heavy-light mesons in HQET factorization through $O (α_{s})$

Saadi Ishaq, Yu Jia, Xiaonu Xiong +1

Analogous to NRQCD factorization for heavy quarkonium exclusive production, in this work we propose to employ the heavy-quark-effective-theory (HQET) factorization, which has been…

Fragmentation function of gluon into spin-singlet $P$ -wave quarkonium

Feng Feng, Saadi Ishaq, Yu Jia +1

Following the operator definition of the fragmentation function developed by Collins and Soper, we compute the gluon-to- $h_{c}$ fragmentation function at the lowest order in the velo…

Polarized forward-backward asymmetries of lepton pair in $B \to K_{1} ℓ^{+} ℓ^{-}$ decay in the presence of New physics

Faisal Munir, Saadi Ishaq, Ishtiaq Ahmed

Double polarized forward-backward asymmetries in $B \to K_{1} (1270, 1400) ℓ^{+} ℓ^{-}$ with $ℓ = μ, τ$ decays are studied, using most general non-standard local four-fer…
