Decay B*+&sub(c) *> D&sup((* ))*+&sub((s))l*+l*- within Covariant Confined Quark Model / M.A.Ivanov, J.N.Pandya, P.Santorelli, N.R.Soni // Physical Review D [Electronic resource]. – 2024. – Vol. 110, No. 9. – P. 096003. – URL: https://doi.org/10.1103/PhysRevD.110.096003. – Bibliogr.: 112.

We study the rare semileptonic decays of 𝐵&sub(𝑐) mesons within the effective field theoretical framework of covariant confined quark model. The transition form factors corresponding to 𝐵*+&sub(𝑐)→𝐷(* )+ and 𝐵*+&sub(𝑐)→𝐷(* )*+&sub(𝑠) are computed in the entire 𝑞*2 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.
