Can colliders disprove leptogenesis?

TL;DR

The paper argues that detecting gauge bosons linked to right-handed currents at colliders could definitively disprove the most common leptogenesis models explaining the universe's matter-antimatter asymmetry.

Contribution

It demonstrates that collider observations of specific gauge bosons can challenge the validity of canonical leptogenesis mechanisms.

Findings

Observation of right-handed gauge bosons would disprove leptogenesis.

Collider experiments can test fundamental cosmological theories.

Provides a new way to falsify leptogenesis models.

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.
