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.
