Study of semileptonic decays of D_{s} meson within R-parity violating supersymmetric model

Abstract

We present the comaprative study of semileptonic and leptonic decays of D_s,D^± and D⁰ meson (D l_α^+l_β^-,D_α^+l_β^-,D_α^+v_α;α,β=e,μ) within the framework of R-parity violating (R_p) Minimal Supersymmetric Standard Model (MSSM). The comparison shows that combination and product couplings (λ_βiαλ_ijq^'∗ or λ_βqk'λ_αjk^'∗) contribution to the branching fractions of the said processes rocesses(under consideration) is consistent or comparable to the experimental measurements in most of the cases. However, there exists some cases, where these contributions are suppressed but still comparable to that of standard model.
