Description
The experimental observations from the colliders
established the standard model (SM), is the most successful phenomenological
framework to explain the non-gravitational interactions of fundamental particles at
high energy. Non-zero neutrino mass and dark matter cast a shadow over its
success. This necessitates the extension of the SM. The most straightforward and
elegant extension of the SM to explain these two phenomena is the Scotogenic
model, where the SM particle spectrum extends with three isospin singlet
right-handed neutrinos and one doublet scalar while all of these being odd under
Z2 symmetry. In this work, we have considered the lightest right-handed neutrino
as the dark matter candidate and freeze-out mechanism for producing observed
dark matter relic density. The charged lepton flavor violation decay processes
constrain the upper side of Yukawa coupling while observed relic density limits the
lower side. We have performed a unique parameterization to attain the highest
possible Yukawa coupling while satisfying LFV and DM constraints. The reduced
number of free parameters and large Yukawa coupling make the model
predictability at lepton colliders very high. Collider phenomenology for possible
signatures performed at lepton colliders and the required luminosities estimated for
detection.
