FERMILAB-COLLIDER. Search for first generation leptoquark pairs in pbar-p collisions at a centre-of-mass energy of 1.8 TeV. Data on (e mu jet) channel froman integrated luminosity of 115 pb-1 collected during 1992-96. There are no can didate events. Data are combined with that from the (ee jets) and (nu mu jets) channels to give 95% CL upper limits to the production cross sections.
