Searching for the Minimal Seesaw Models at the LHC and Beyond

Figure 26

Bounds on the square of the mixing angle from the trilepton plus MET final state as a function of the heavy neutrino mass . The shaded region is ruled out by the EWPD and Higgs data. Prospective bounds from the Higgs data had been calculated in [45] for the LHC at the high luminosity  fb⁻¹ and future  TeV pp collider.
