Breaking classical Lie groups to finite subgroups - an automated approach
Maximilian Fallbacher
The decomposition of representations of compact classical Lie groups into representations of finite subgroups is discussed. A Mathematica package is presented that can be used to c…
Anomaly-safe discrete groups
Mu-Chun Chen, Maximilian Fallbacher, Michael Ratz +2
We show that there is a class of finite groups, the so-called perfect groups, which cannot exhibit anomalies. This implies that all non-Abelian finite simple groups are anomaly-fre…
Symmetries of symmetries and geometrical CP violation
Maximilian Fallbacher, Andreas Trautner
We investigate transformations which are not symmetries of a theory but nevertheless leave invariant the set of all symmetry elements and representations. Generalizing from the exa…
CP Violation from Finite Groups
Mu-Chun Chen, Maximilian Fallbacher, K. T. Mahanthappa +2
We discuss the origin of CP violation in settings with a discrete (flavor) symmetry . We show that physical CP transformations always have to be class-inverting automorphisms of…
Predictivity of models with spontaneously broken non-Abelian discrete flavor symmetries
Mu-Chun Chen, Maximilian Fallbacher, Yuji Omura +2
In a class of supersymmetric flavor models predictions are based on residual symmetries of some subsectors of the theory such as those of the charged leptons and neutrinos. However…
Supersymmetric unification and R symmetries
Mu-Chun Chen, Maximilian Fallbacher, Michael Ratz
We review the role of R symmetries in models of supersymmetric unification in four and more dimensions, and in string theory. We show that, if one demands anomaly freedom and fermi…
