Phenomenology of Top Partners at the ILC

Abstract

The assumption of a new symmetry provides a nice explanation of the existence of dark matter and an elegant way to avoid the electroweak constraints. This symmetry often requires the pair production of new particles at colliders and it guarantees that cascade decays down to the lightest particle give rise to missing energy plus jets and leptons. For a long time, supersymmetry with the conserved R-parity was the only candidate for such signals. However, any new physics with this type of new symmetry may show up with similar signals and the discrimination between different models at the LHC is quite challenging. In this paper, we address the problem of discrimination between different models, more concretely, in the little Higgs theory with T-parity (LHT) and the supersymmetric theory with R-parity. We concentrate on the pair production of heavy top partners, e.g., T-odd quarks in LHT and the scalar top quarks in the MSSM at linear colliders (LC).
