Processes with high transverse momentum leptons and jets
are predicted by many Beyond the Standard Model (BSM)
scenarios including leptoquarks, Left-Right Symmetry and
various models of Grand Unification. 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 more elegant description of the fundamental
forces. I will present preliminary results of studies performed with the ATLAS detector at the LHC, where we attempt to address questions about the origin of masses and the nature of the known neutrinos, the origin of CP violation and its role in baryogenesis, the origin of flavor and other fundamental questions beyond EWSB.
