Search for Heavy Neutrinos and W_R in Events with Deleptons and Jets

The discovery of neutrino oscillations established that neutrinos have non-zero mass and provided clear evidence for physics beyond the Standard Model. One possible explanation for the mass of light neutrinos is provided by theoretical models based on ideas of Grand Unification. Such models usually introduce additional neutrino fields, which manifest themselves as the new heavy particles that could be detected directly. In this poster we describe a search for hypothetical heavy neutrinos and right-handed gauge bosons in events with two high transverse momentum leptons and at least one high transverse momentum hadronic jet. The results were obtained from data corresponding to an integrated luminosity of 2.1/fb collected in 2011 in proton-proton collisions at 7 TeV with the ATLAS detector at the CERN Large Hadron Collider.
