Can colliders disprove leptogenesis?

Abstract

While leptogenesis is a very solid but hard to check contender for the generation of the observed excess of baryons over anti-baryons in the Universe, we show that the observation of gauge bosons associated with right-handed currents at present or future colliders would suffice to disprove its most canonical mechanism.
