Form factors and branching fraction calculations for $$B_s \rightarrow D_s^{(*)} \ell ^+ \nu _\ell$$ in view of LHCb observation

Rare decays of 𝐵𝑐 mesons

“…Rare decays of B c meson Akshay N. Gadaria years, we have been successful in utilising present formalism for the very detailed analysis of different weak observables for charmed [13][14][15][16][17][18][19] as well as bottom hadrons [20][21][22][23][24]. In the present work, we have studied the rare weak decays of B c mesons induced by the b → s transition at quark level.…”

Ensuring the Efficiency of the Institute of Private Bailiffs in the Republic of Kazakhstan

“…The purpose of this paper is to extend our model and predict a model parameters of unobserved B * c . We studied b → c, b → s and b → d(u) transitions in the framework of covariant confined quark model(CCQM) in our previous works [26][27][28][29][30].…”
