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.
