New Limits on R–Parity Breakings in Supersymmetric Standard Models
New limits on couplings λjk , which break both the baryon number and the R–parity, are derived by using a new mechanism that contributes to the neutronanti-neutron oscillation. The constraints due to proton decay and its potential phenomenology are also reexamined. The minimal supersymmetric standard model (MSSM) [1] has been widely considered as a leading candidate for new physics beyond Stand...
متن کاملR-Parity Violating Minimal Supersymmetric Standard Model
We show that the present experimental limits on electron-nucleon interactions that violate both parity and time reversal invariance provide new stringent bounds on the imaginary parts of some of the products of the R-parity violating coupling constants in the R-parity violating Minimal Supersymmetric Standard Model. 11.30.Er,12.60.Jv,32.10.Dk Typeset using REVTEX
متن کاملR-parity in Supersymmetric Left-right Models
Although the Standard Model (SM) gives very good results in explaining the observed properties of the charged fermions, it is unlikely to be the ultimate theory. It maintains the masslessness of the neutrinos to all orders in perturbation theory, and even after non-pertubative effects are included. The recent groundbreaking discovery of nonzero neutrino masses and oscillations 1 has put massive...
متن کاملDuality of a Supersymmetric Standard Model without R parity
Recently one of the authors proposed a dual theory of a Supersymmetric Standard Model (SSM), in which it is naturally understood that at least one quark (the top quark) should be heavy, i.e., almost the same order as the weak scale, and the supersymmetric Higgs mass parameter μ can naturally be expected to be small. Unfortunately, the model cannot possess Yukawa couplings of lepton sector. In t...
متن کاملR-parity violating U(1)-extended supersymmetric standard model
Supersymmetry is one of the best motivated new physics scenarios. To build a realistic supersymmetric standard model, however, a companion symmetry is necessary to address various issues. While R-parity is a popular candidate that can address the proton and dark matter issues simultaneously, it is not the only option for such a property. We review how a TeV scale U(1) gauge symmetry can replace...
