We present a search for tt production in events having dielectron final states in 120.2 ± 6.5 pb -1 of pp collisions at s = 1.8 TeV using the DØ detector. This analysis has been optimized to search for a heavy top quark (ie. m top > 140 GeV/c 2 ). One candidate event is seen with a background estimated to be 0.82 ± 0.08 events, giving a cross section of 0.9 ± 5.0 pb if m top = 170 GeV/c 2 . Therefore, no conclusive evidence for top production is seen in this channel. Assuming the candidate isdoi:10.2172/1372287 fatcat:gbibjuckgvcx3oo5lx454nx57y
