| Abstract: |
It is generally believed that new TeV scale particles that help addressing the hierarchy problem, i.e. stop in the MSSM or heavy top partner in little Higgs models, can be discovered at the LHC. However, there are models that suggest otherwise. Twin Higgs could be one of the examples. We study the collider signal of the left-right twin Higgs model in the limit that the right-handed neutrino mass is less than the mass of the right-handed gauge boson. In this limit, new leptonic decay chains open up, allowing the discovery of particles that regularize the one-loop quadratic divergences of the Higgs. Half of these events contain same-sign leptons without missing energy, which have no genuine standard model background and therefore provide a clean signal for discovery |
