abstract
The discovery potential of the ATLAS detector for scalar leptoquark pair production at the LHC is discussed in this paper. The study is performed using a parameterized yet realistic simulation of the ATLAS detector response for the signal and the background. The channel LQLQ->(lq)(lq),where l=e,mu, is investigated for the first two generations and the decay mode LQLQ->(nu_tau b)(nu_tau b) for the third one. In both cases, a preliminary mass reach is found to be ~1.3 TeV for three years of LHC running at low luminosity.
