Description
We investigate the displaced vertex scenarios in the case of Type-III and Type-I scenarios at the LHC, MATHUSLA and muon colliders. Seesaw mechanisms are motivated to explain small but tiny neutrino masses, and as a result we expect heavy charged or neutral fermions to exist. These heavy fermions tend to have displaced decay due to rather small Yukawa couplings. However, LHC being a machine where the partons collide with their momentum according to the parton distribution function. Often due to higher longitudinal boost such decays are more displaced towards the $Z$-axis as compared to the perpendicular directions. We performed a comparative study of the longitudinal and transverse boost and probed the regions of parameter space at the LHC and FCC for energies of 14, 27 and 100 TeV. On the contrary, at a muon collider though the momentum is constant at each event, transverse momentum tends to diverge. We analyse such features and draw regions that can be probed by present and future colliders.
