Simulations of R-parity Violating SUSY Models
In recent years there has been a great deal of interest in R-parity violating supersymmetric models. We explain the motivation for studying these models and explore the various phenomenological consequences of R-parity violation. In particular, we argue that if we are to explore all channels for the discovery of supersymmetry then these models must be investigated. It has become essential for t...
متن کاملSleptons in R-parity Violating Susy
In R-parity violating SUSY models sleptons can be produced singly in ee and qq̄ collisions. The formation of slepton resonances at LEP2 or Tevatron at current energies is an exciting possibility. Existing LEP2 and Tevatron data can be exploited to look for sleptons and , if unsuccessful, to derive bounds on the Yukawa couplings of sleptons to quark and lepton pairs.
متن کاملRb Bounds On R-Parity Violating SUSY
We evaluated the contribution of R-parity violating interactions to Zbb̄ coupling in the minimal supersymmetric model. The R-violating interactions involving the top quark are found to give large contribution to Zbb̄ coupling and, therefore, subject to new stringent constraints from Rb. The current limits on some of these couplings are much improved by the latest Rb data. Typeset using REVTEX
متن کاملMulti-parameter approach to R-parity violating SUSY couplings
We introduce and implement a new, extended approach to placing bounds on trilinear Rparity violating (R/ ) couplings. We focus on a limited set of leptonic and semi-leptonic processes involving neutrinos, combining multidimensional plotting and cross-checking constraints from different experiments. This allows us to explore new regions of parameter space and to relax a number of bounds given in...
متن کاملFlavor-changing top quark decays in R-parity-violating SUSY
The flavor changing top quark decays t → cV (V = Z, γ, g) induced by R-parity-violating couplings in the minimal supersymmetric model are evaluated. We find that Br(t → cV ) can be enhanced significantly relative to that in the SUSY model with R-parity. Our results show that Br(t → cg) ∼ 10, Br(t → cZ) ∼ 10 and Br(t → cγ) ∼ 10, which are observable at the upgraded Tevatron and the LHC. PACS: 14...
