Branching Ratio Anomalies from R-Parity Violation
نویسنده
چکیده
The branching ratios for the neutral and charged B decay channels to ηK and ηK are well above the Standard Model expectations. Moreover, the mixing-induced CP asymmetry in B → φKS is incompatible to that found in B → J/ψKS . We investigate whether a flavourspecific tree-level b → sss operator coming from R-parity violating supersymmetry can resolve both these discrepancies, without jeopardizing those results which are in agreement with the Standard Model. We found that it is possible to have a parameter space satisfying all these requirements, including that of a low strong phase difference compatible with the color transparency argument. Furthermore, we put a robust bound on the relevant coupling, which is two orders of magnitude better than the existing one. PACS number(s): 11.30.Fs, 12.60.Jv, 13.25.Hw

Bilinear R-parity Violation in Rare Meson Decays
Abstract. We discuss rare meson decays K → πll and D → Kll (l, l = e, μ) in a supersymmetric extension of the standard model with explicit breaking of R-parity by bilinear Yukawa couplings in the superpotential. Estimates of the branching ratios for these decays are given. We also compare our numerical results with analogous ones previously obtained for two other mechanisms of lepton number vio...
متن کاملLepton Number Violation in Decays of Supersymmetric Particles
We discuss lepton flavour violating signals at the LHC in the framework of supersymmetric theories. We consider R-parity conserving as well as R-parity violating scenarios. In the case of R-parity conservation we show that in decays of supersymmetric particles large regions in parameter exist where lepton flavour violating decay modes have large branching ratios despite the stringent constraint...
متن کاملNovel Scalar Boson Decays in Susy with Broken R-parity
R parity violation can induce mixing of the supersymmetric Higgs bosons with the sneutrinos at the tree level. We study the effect of this mixing on the decays of Higgs scalars as well as sneutrinos in an effective model where the violation of R parity is included in the minimal supersymmetric model through bilinear lepton number violating superpotential terms. We show that a small violation of...
متن کاملul−νl decays in the MSSM with and without R-parity violation
We study the exclusive b → ulνl (l = τ, μ, e) decays in the MSSM with and without R-parity violation. From the experimental measurements of branching ratios B(B− u → τ−ντ ), B(B− u → M lνl′) and B(B 0 d → M lνl′) (l′ = μ, e, M ′ = π, ρ), we derive new upper bounds on the relevant new physics parameters within the decays. Using the constrained new physics parameter spaces, we predict the charged...
متن کاملProbing neutrino properties with charged scalar lepton decays
Supersymmetry with bilinear R-parity violation provides a predictive framework for neutrino masses and mixings in agreement with current neutrino oscillation data. The model leads to striking signals at future colliders through the R-parity violating decays of the lightest supersymmetric particle. Here we study charged scalar lepton decays and demonstrate that if the scalar tau is the LSP (i) i...
