Title: Search for the top quark from (e,{mu}) and (e,e) events in the D0 detector in p{bar p} collisions at {radical}s = 1.8 TeV

Abstract

We present results from searches for top quark production in p{bar p} collisions at the Tevatron collider based on an integrated luminosity of 7.5 pb{sup {minus}1} obtained during the 1992--1993 ran. The present results are confined to decay modes where both the top and anti-top quarks in the event decay semi-leptonically to the ee and e{mu} channels. A lower limit of 103 (99) GeV/c{sup 2} is obtained at 95% confidence level for the top quark mass from the absence of events consistent with standard model top quark decays with background subtraction (no background subtraction). We do however observe one event in the e{mu} channel which cannot be explained by the known backgrounds. While we make no claim that this event is due to top quark decay, it is not inconsistent with a top quark mass in the range 130--170 GeV/c{sup 2}
