Abstract

This thesis describes a search for hypothetical heavy neutrinos, N, and right-handed gauge bosons, WR, in events with two high transverse momentum muons and at least one high transverse momentum hadronic jet. The results were obtained from data corresponding to an integrated luminosity of 4.7 fb^{-1} collected in proton-proton collisions at sqrt{s}=7 TeV with the ATLAS detector at the CERN Large Hadron Collider. No excess above the Standard Model background expectation is observed. Excluded mass regions for Majorana neutrinos are presented in the framework of Left-Right Symmetric Model which introduces interactions that violate lepton and lepton-flavor numbers. The results described in this thesis represent limits on the masses of heavy neutrinos and WR bosons obtained in direct searches.
