Prospects for early discoveries in final states with dileptons, jets and no missing energy: LRSM and Lepto-Quarks

Final states with high pT leptons and jets are predicted by many Beyond the Standard Model(BSM) scenarios including Grand Unification Theories, Left-Right- Symmetry and Technicolor. Studies based on fully simulated data samples containing two or more high pT leptons, jets and no missing energy have been performed in view of searching for BSM physics with a few hundred inverse picobarns of early ATLAS data. The prospects for an early discovery of first and second generation leptoquark pairs, and of right-handed W and heavy neutrinos will be shown.
