Supersymmetry can be combined with R-symmetry, a continuous

U(1) symmetry which does not commute with SUSY. R-symmetric models can

be phenomenologically viable. In recent years, the minimal R-symmetric

model (MRSSM) has been studied in detail. Two appealing properties are:

(1) the MRSSM is distinct from the usual MSSM in the sense that the

MRSSM does not possess an MSSM-like limit; (2) the MRSSM has fewer

parameters than the MSSM. One might therefore call the MRSSM an even

more minimal realization of SUSY. In the colloquium we will introduce

this model and provide an overview and a discussion of its properties.

It has turned out that the model has surprisingly rich and

phenomenologically successful properties. We will focus in particular on

its prediction for the Higgs boson mass, electroweak precision

observables, dark matter, LHC mass limits, and muon observables.
