Search for top in D-Zero using the electron + jets channel with soft muon tagging

TL;DR

This paper reports on a search for the top quark in D-Zero using electron + jets events with soft muon tagging, combining multiple channels, but finds no significant evidence of top quark production.

Contribution

It introduces a method for top quark search using soft muon tagging in the electron + jets channel and combines results from multiple channels for analysis.

Findings

No significant top quark signal detected.

Top cross section and error as a function of top mass presented.

Analysis based on 13.5 pb-1 of data.

Abstract

We present preliminary results for the search for the top quark in D-Zero in the electron + jets channel where one of the b quark jets is tagged by means of a soft muon, using 13.5 pb-1 of data. Standard model decay modes for the top quark are assumed. We present the resulting top cross section and error as a function of top mass using this channel combined with the dilepton channel and the untagged lepton + jets channel . At present, no significant signal for top quark production can be established.
