Query: Scalar Leptoquark Pair Production at the CERN LHC: Signal and
  Backgrounds   We present the results of an analysis for the pair production of scalar
leptoquarks at the CERN Large Hadron Collider (LHC) with energy=14 TeV and
luminosity=10 fb^{-1} which includes the dominant sources of Standard Model
background associated to this process: top-antitop, ZZ, WZ and Z*jj production.
The top-antitop process provides the main source of background. We consider
leptoquarks introduced in the framework of a superstring-inspired E_6 model.
The leptoquark production is found to be dominant in all regions of parameter
space for leptoquark masses below 750 GeV. We establish the discovery reach of
the leptoquarks at 750 GeV (1 TeV) for a branching ratio of B(LQ -> eq)=0.5
(B=1).
