    Search for pair production of first-generation leptoquarks in p anti-p collisions at s**(1/2) = 1.96-TeV

  • Original language description

    A search for pair production of first-generation leptoquarks LQ is performed with data collected by the D0 experiment in p pbar collisions at sqrt(s)=1.96 TeV at the Fermilab Tevatron Collider. In a sample of data corresponding to 1 fb-1, the search hasbeen performed on the final states with two electrons and two jets or one electron, two jets and missing transverse energy. We find our data consistent with standard model expectations. The results are combined with those found in a previous analysis ofevents with two jets and missing transverse energy to obtain scalar LQ mass limits. We set 95% C.L. lower limits on a scalar LQ mass of 299 GeV, 284 GeV and 216 GeV for beta=1, beta=0.5 and beta=0.02 respectively, where beta is the LQ branching ratio inthe eq channel.
