Working with the most general $SU(2)_L \otimes U(1)_Y$ invariant leptoquark interactions, we analyze in detail the signals and backgrounds that lead to a final state containing a pair $e^+e^-$ and jets. Our results indicate that a machine like the LHC will be able to discover leptoquarks with masses up to 2--3 TeV depending on their couplings.37 pages, revtex, uses epsfig.sty (included), 15 figures (included)High Energy Physics - PhenomenologySignal and Backgrounds for Leptoquarks at the LHCtext
