New signs of supersymmetry: the R-axion

Is there any generic sign of supersymmetry, that has not yet been satisfactorily explored? In this talk I will argue that the answer is yes in the particle of the R-axion, the pseudo-Goldstone boson of the U(1)^R symmetry, and I will motivate experimental searches in light of this observation. I will focus on R-axion masses in the GeV to TeV range, which are relevant for hadron and (future) lepton colliders, as well as for flavour factories. Current bounds allow for the exciting possibility that the R-axion will be the first sign of SUSY to show up at such experiments. The considerations developed here open new directions in phenomenology and model building, that are still to be explored.
