| dc.description | We have searched for the pair production of first generation scalar leptoquarks using the full data set (123 pb**-1) collected with the D0 detector at the Fermilab Tevatron during 1992-1996. We observe no candidates, consistent with the expected background. We combine these new results from the ee + jets and enu + jets channels with the published nunu + jets result to obtain a 95% CL upper limits on the LQ pair production cross section as a function of mass and beta, the branching ratio to a charged lepton and a quark. Comparing to the NLO theory predictions, we set 95% CL lower limits on the LQ mass of 225, 204, and 79 GeV/c**2 for beta=1, 1/2, and 0, respectively. The results of this analysis rule out an interpretation of the excess of high Q**2 events at HERA as leptoquarks with LQ mass below 200 GeV/c**2 for values of beta > 0.4. | |
