Description
Heavy neutral leptons (HNLs) and axion-like particles (ALPs) are both well-motivated candidates for beyond the Standard Model (BSM) physics. ALPs with couplings to gluons can be abundantly produced at the LHC. Therefore, HNLs produced via the ALP portal may provide unprecedented sensitivity to HNL parameters. In this talk, I will present the sensitivities of ATLAS and future far detectors to these long-lived HNLs at the high-luminosity LHC, considering different ALP mass regimes and their distinct phenomenological features and theory consideration.
