Measuring the parameters of an HNL model at FCC-ee
Description
Based on formalism of the recently proposed pSPSS model for heavy neutral
leptons (HNLs), we study the possibility of measuring the oscillations of HNLs at the FCC-
ee with a parametrised detector simulation. We further discuss strategies for discrimination
of the Dirac or Majorana nature of the HNLs, and we assess how this strategy can be applied
to constrain the parameters of the model in the parameter space in which the oscillation
may not be observable.
