Decay Bc+ → D (s) (∗)+ ℓ+ℓ- within covariant confined quark model M. A. Ivanov, J. N. Pandya, P. Santorelli, N. R. Soni Physical Review D, 2024 We study the rare semileptonic decays of Bc mesons within the effective field theoretical framework of covariant confined quark model. The transition form factors corresponding to Bc+→D(*)+ and Bc+→Ds(*)+ are computed in the entire q2 range. Using form factors, we compute the branching fractions and compare them with the available theoretical results. We also compute various physical observables such as forward-backward asymmetry, longitudinal and transverse polarizations, as well as clean angular observables.

Reply to "comment on 'Brownian motion with time-dependent friction and single-particle dynamics in liquids' " Kirit N. Lad, Margi K. Patel, Arun Pratap, Jignesh N. Pandya Physical Review E, 2023 In this reply, we respond to the comments by Lisý and Tóthová (LT) on our recent work [Phys. Rev. E 105, 064107 (2022)10.1103/PhysRevE.105.064107], where we have extended the microscopic theory of molecular motion in atomic liquids that was originally proposed by Glass and Rice [Phys. Rev. 176, 239 (1968)10.1103/PhysRev.176.239]. Contrary to our conclusion of nonavailability of a physically tractable analytical solution of the equation of motion involving dynamic friction, LT have attempted to obtain an analytical solution giving the velocity autocorrelation function in liquids. We show that the analytical solution of the equation of motion derived by LT is incomplete and not an appropriate solution for the description of atomic dynamics in liquids. It is demonstrated that the generalized statements made by LT regarding the equation of motion giving incorrect results are unjustified in the absence of substantial proofs. Also, until and unless proven otherwise, we do not find any reason for the reconsideration of the theory as suggested by LT.
Weak rare decays for B → ω transitions within covariant confined quark model framework Nakul R. Soni, Aidos Issadykov, Akshay N. Gadaria, Janaki J. Patel, Jignesh N. Pandya Aip Conference Proceedings, 2021 We present the branching fractions for the rare semileptonic decay B→ωl+l− for l=e,μ,τ. The necessary transition form factors are computed in the entire range of momentum transfer within the Standard Model framework of Covariant Confined Quark Model with built-in infra-red confinement. We further compute different physical observables such as forward backward asymmetry, longitudinal and transverse polarization along with other angular observables.
