Abstract

We present the results of a search for first generation scalar leptoquarks pairs (S₁S®₁) in 110 ± 7 pb⁻¹ of data collected by the Collider Detector at Fermilab. We assume both leptoquarks decay to an electron and a quark. Three candidate events, with masses below 140 GeV/c² and consistent with background expectations, are observed. We obtain a 95% confidence level upper limit on the production cross section as a function of the leptoquark mass. Using a next-to-leading order calculation of S₁S®₁ production, we exclude scalar leptoquarks with mass less than 213GeV/c² at 95% C.L. for a branching ratio into eq equal to 1.
