Discrete Symmetries in the MSSM
Roland Schieren
The use of discrete symmetries, especially abelian ones, in physics beyond the standard model of particle physics is discussed. A method is developed how a general, abelian, discre…
Discrete R symmetries for the MSSM and its singlet extensions
Hyun Min Lee, Stuart Raby, Michael Ratz +4
We determine the anomaly free discrete R symmetries, consistent with the MSSM, that commute with SU(5) and suppress the parameter and nucleon decay. We show that the order M of…
String-derived MSSM vacua with residual R symmetries
Rolf Kappl, Bjoern Petersen, Stuart Raby +3
Recently it was shown that there is a unique Z_4^R symmetry for the MSSM which allows the Yukawa couplings and dimension five neutrino mass operator, forbids the mu term and commut…
A unique Z_4^R symmetry for the MSSM
Hyun Min Lee, Stuart Raby, Michael Ratz +4
We consider the possible anomaly free Abelian discrete symmetries of the MSSM that forbid the mu-term at perturbative order. Allowing for anomaly cancellation via the Green-Schwarz…
Patterns of remnant discrete symmetries
Bjoern Petersen, Michael Ratz, Roland Schieren
We analyze patterns of remnant discrete symmetries that arise from U(1)^N theories by spontaneous breaking. We describe a simple, geometrical way to understand these patterns and p…
Running minimal flavor violation
Paride Paradisi, Michael Ratz, Roland Schieren +1
We consider the flavor structure of the minimal supersymmetric standard model (MSSM) in the framework of `minimal flavor violation' (MFV). We show that, if one imposes the MFV stru…
