Study of pure and semileptonic decays of Ds meson within R-parity violating supersymmetric model

  • We present the comaprative study of semileptonic and leptonic decays of Ds,D± and D0 meson ( D→ M lα +lβ-,D→lα+lβ-,D→lα+vα ;α,β=e,μ) within the framework of R-parity violating the (Rp) Minimal Supersymmetric Standard Model (MSSM). The comparison shows that combination and product couplings, (λβiαλ'ijq* or λ'βqk*λ'α jk*) contribution to the branching fractions of the said processes (under consideration) is consistent with or comparable to the experimental measurements in most of the cases. However, some cases exist where these contributions are highly suppressed. We identify such cases in our analysis and single out the important ones suitable for exploring in the future and current experiments.

Study of pure and semileptonic decays of Ds meson within R-parity violating supersymmetric model

Abstract: We present the comaprative study of semileptonic and leptonic decays of Ds,D± and D0 meson ( D→ M lα +lβ-,D→lα+lβ-,D→lα+vα ;α,β=e,μ) within the framework of R-parity violating the (Rp) Minimal Supersymmetric Standard Model (MSSM). The comparison shows that combination and product couplings, (λβiαλ'ijq* or λ'βqk*λ'α jk*) contribution to the branching fractions of the said processes (under consideration) is consistent with or comparable to the experimental measurements in most of the cases. However, some cases exist where these contributions are highly suppressed. We identify such cases in our analysis and single out the important ones suitable for exploring in the future and current experiments.
