  The presence of small neutrino masses and flavour mixings can be accounted
for naturally in various models about extensions of the standard model,
particularly in the seesaw mechanism models. In this work, we present a
minimally extended seesaw framework with two right-handed neutrinos, where the
active neutrino masses are derived in the radiative regime. Using the framework
it can be shown that within certain mass limits, the light neutrino mass term
can approach a form that is similar to its form under the type-I seesaw
mechanism. Apart from this, we show that the decay width of right-handed
neutrinos (produced through the decay of W boson in a particle collider) is
short enough to cause a sufficiently long lifetime for the particles, thus
ensuring an observable displacement in the LHC between the production and decay
vertices. We comment on the fact that these displaced vertex signatures thus
can serve as a means to verify the existence of these right-handed neutrinos in
future experiments. Lastly, we line up the possibility of our future work where
the vertex signatures of particles greater than the mass of W boson can be
worked upon.
