Description
Axion-like particles (ALPs) and heavy neutral leptons (HNLs) are both well-motivated extensions of the Standard Model. Their interaction offers an exquisite opportunity to unveil the nature of HNLs, even if they had tiny Seesaw-like mixing angles, which would make them almost impossible to test otherwise at collider. In this work, we point out a particularly clean process, the JALZ, which offers such a unique opportunity. We estimate its current and future sensitivity at the LHC.
