Leptoquark pair production at the Fermilab Tevatron: Signal and backgrounds

We perform a simulation of scalar leptoquark pair production at the Fermilab Tevatron $(\sqrt{s}=1.8\mathrm{}$ TeV and $\mathcal{L}=100\mathrm{}$ pb${}^{-1})$ with ISAJET. We also investigate the dominant sources of standard model background: $Z^{*}\mathrm{jj}$, $\mathrm{ZZ}$, $\mathrm{WZ}$ production and heavy quark $t\overline{t}$. We find that the $Z^{*}\mathrm{jj}$ background is dominant. We also evaluate the signal-to-background ratio and find a discovery reach of 130 GeV (170 GeV) for a branching ratio of $B(LQ\to eq)=0.5\mathrm{}$ $\mathrm{}(B=1\mathrm{})\mathrm{}$.
