Decay Ds+→ϕl+vl$ D_s^ + \to \varphi l^ + v_l $ in Covariant Quark Model
Wepresent the branching fractions for the leptonic and semileptonic decays Ds+→l+vl$ D_s^ + \to l^ + v_l $ for ℓ = e,µ,τ and Ds+→ϕl+vl$ D_s^ + \to \varphi l^ + v_l $ for ℓ = e,µ. We use the covariant confined quark model with built-in infrared confinement for computation of required transition...
