Description

In the context of the Phenomenological Type I Seesaw, we investigate the LHC's sensitivity to exclusive, mesonic decay modes of long-lived, light (Dirac and Majorana) heavy neutrinos $N$ when they are produced in the decays of $W^\pm$ bosons. We present a new framework that combines massless QCD to describe $N$'s production up to NLO in QCD via weak bosons with a low-energy effective field theory to describe $N$'s decays to mesons. We provide a prescription for fast, numerical determination of $N$'s partial and total widths for any mass and accounts for mesonic decay modes.
