R-parity violation

Nuclear Physics B - Proceedings Supplements, 1997
The occurrence of fixed points in the renormalization group evolution of R -parity-violating (RPV) couplings in the minimum supersymmetric standard model (MSSM) is quantified, assuming that third generation couplings are dominant. These fixed points give new upper bounds on the RPV couplings at the electroweak scale.

R-Parity “Я” us Rochester

AIP Conference Proceedings, 1998
R-parity violating terms in the minimal supersymmetric extension of the Standard Model are studied within a parametrization characterized by a single vacuum expectation value for the scalar components of the Y=−1/2 superfields. The benefits of this efficient parametrization are that it enables phenomenological analyses of R-parity violation without a ...

R-parity-violating Yukawa couplings

1996
We discuss the evolution of R-parity-violating (RPV) couplings in the minimum supersymmetric standard model, assuming a hierarchy for coupling strengths and emphasising solutions where R-conserving and R-violating top quark Yukawa couplings both approach infrared fixed points.
