Description
Final states with leptons and jets of high transverse momenta are predicted by many Beyond the Standard Model (BSM) scenarios including leptoquarks, Left-Right Symmetry and various implementations of Grand Unification Theory (GUT). Such theoretical models extend the application of Quantum Field Theory to energies far above the Electroweak Symmetry Breaking (EWSB) energy scale and seek to provide a much more elegant and symmetric description of the fundamental forces. The predictions of such models include the explanations for the masses of known neutrinos, the origin of CP violation and its role in baryogenesis, the origin of flavour and other fundamental questions beyond EWSB. In my presentation I will describe the studies of dilepton-jets final states that could be used to search for BSM physics with a few hundred inverse picobarns of early ATLAS data. The presented analyses are based on fully-simulated data samples that contain two or more lepton candidates and jets of high transverse momenta. I will discuss some experimental issues important for the studied final states and will present the prospects for heavy neutrinos discovery with early ATLAS data.
