Improving the Hadron Physics of Non-Standard-Model Decays: Example Bounds on R-parity Violation
نویسندگان
چکیده
Using the example of selected decays driven by R-parity-violating supersymmetric operators, we demonstrate how strong final-state interactions can be controlled quantitatively with high precision, thus allowing for a more accurate extraction of effective parameters from data. In our examples we focus on the lepton-flavor-violating decays τ → μπ+π−. In R-parity violation these can arise due to the product of two couplings. We find bounds that are an order of magnitude stronger than previous ones.

CP Violating B Decays with R-parity Violation
We study CP violating B decays in the minimal supersymmetric standard model with R-parity violation. We estimate how much R-parity violation modifies the SM predictions for CP asymmetries in B decays within the present bounds. The effects of R-parityand lepton-number-violating couplings on the ratio of the decay amplitude due to R-parity violation to that of the SM can differ by one or two orde...
متن کامل5 Puzzles in B → ππ , πK decays : Possible implications for R - parity violating supersymmetry
Recent experiments suggest that certain data of B → ππ, πK decays are inconsistent with the standard model expectations. We try to explain the discrepancies with R-parity violating suppersymmetry. By employing the QCD factorization approach, we study these decays in the minimal supersymmetric standard model with R-parity violation. We show that R-parity violation can resolve the discrepancies i...
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 کاملDecays with R-parity Violation
We derive the upper bounds on certain products of R-parityand leptonflavor-violating couplings from B → Xsli lj − decays. These modes of Bmeson decays can constrain the product combinations of the couplings with one or more heavy generation indices which are comparable with or stronger than the present bounds. From the studies of the invariant dilepton mass spectrum and the forward backward asy...
متن کاملBs Mesons in the MSSM with R-parity Violation
Motivated by the possible large direct CP asymmetry of B̄0 d → D + D − decay measured by Belle collaboration, we investigate double charm Bu,d and Bs decays in the minimal supersymmetric standard model with R-parity violation. We derive the bounds on relevant R-parity violating couplings from the current experimental data, which show quite consistent measurements among relative collaborations. U...
