Constraints on Heavy Neutral Leptons interacting with a singlet scalar

Guillermo Gambini

McGill & Campinas State

Experimental results constrain our models to explain new physics, but these limits are not set in stone. In this talk I will present a reinterpretation of the results published by the DELPHI, Belle, and CHARM collaborations when heavy neutral leptons couple to a light singlet scalar. A new method for reproducing the existing limits from these collider experiments will be presented.
