Abstract
We report on a search for first generation leptoquarks with the Dnull set detector at the Fermilab Tevatron <p(p)over bar> collider at root s = 1.8 TeV. This search is based on 15 pb(-1) of data. Leptoquarks ar e assumed to be produced in pairs and to decay into an electron + quar k with branching ratio P. No leptoquark candidates were found. We obta in cross section times branching ratio limits as a function of leptoqu ark mass. For pair production of scalar leptoquarks, we set a leptoqua rk mass limit of 133 GeV for beta = 1 and 120 GeV for beta = 0.5 at 95 % confidence level.
