The Hunting of the MR Model

Abstract

We consider experimental signatures of the standard model's minimal supersymmetric extension with a continuous $U(1{)}_R$ symmetry (MR model). We focus on the ability of existing and planned electron-positron colliders to probe this model and to distinguish it from both the standard model and the standard model's minimal supersymmetric extension with a discrete $R$-parity.
