Serban Protopopescu (Brookhaven National Laboratory, for the D-Zero, Collaboration)
TL;DR
This paper reports a search for top quark pair production in proton-antiproton collisions at 1.8 TeV, using a topological tagging method, but finds no statistically significant excess above background.
Contribution
It introduces a topological tagging approach to identify top quark events in lepton + jets final states at the Tevatron.
Findings
No significant excess observed in e+jet and mu+jet channels.
Background estimates agree across methods.
Results are preliminary and consistent with standard model expectations.
Abstract
We have searched for production of t-tbar pairs in p-pbar interactions at 1.8 TeV center-of-mass energy at the FNAL Tevatron collider. The search assumes standard model decay for top quark into W + b quark. We observe in e+jet and mu+jet final states a small, not statistically significant, excess above the background estimated by two different methods. The results presented are preliminary.
