Abstract

We study the feasibility and advantages of investigating the c→ s decay channel of the B_c meson through the cascade decay B_c→ B_sπ, B_s→ D_sℓν. We take into account possible contaminations coming from the vector excitations (like B_s^*, D_s^* or ρ in the intermediate stages of the cascade) too, as well as the opposite cascade B_c→ B_sℓν, B_s→ D_sπ. We show how the p_T distribution of the pion and the lepton can possibly help to differentiate between various form factor models, for which we either need more integrated luminosity at the LHC, or a high-luminosity e⁺e^- B factory producing B_c mesons too.
