Search for first generation leptoquarks in proton-antiproton collisions at the center of mass energy = 1.96 TeV in the dielectron + dijet channel using the D0 detector at Fermilab
- Columbia Univ., New York, NY (United States)
We describe a search for first generation leptoquarks decaying into the eejj final state in $$p\bar{p}$$ collisions at a center of mass energy of 1.96 TeV using the D0 detector at the Fermilab Tevatron. this search is based on data collected during 2002-2003 with an integrated luminosity of (130.4 =- 8.5) pb -1. Leptoquarks are assumed to be produced in pairs and to decay into an electron and a quark with a branching ration β. We observe no evidence for leptoquarks, and set an upper cross section limit of 0.086 pb at the 95% confidence level corresponding to a lower mass limit of 231 GeV/c2 for scalar leptoquarks when β = 1.
