SCALAR THREE-BODY DECAYS AND SIGNALS FOR NEW PHYSICS
/ Authors
/ Abstract
If massive invisible particles are pair-produced in a three-body decay, the energy distribution of the other (visible) product will be sensitive to the mass of the invisible pair. We discuss the implications of this fact in the contexts of a Higgs boson decaying into (i) a Z-boson and two massive neutrinos of a fourth generation, and (ii) a Z and two lightest supersymmetric particles in the minimal supersymmetric standard model.
