The Top Quark in Muon + Jet Events from 1.8-TeV $$p\bar{p}$$ Collisions
- Hawaii U.
An optimized search for the top (or truth) quark is performed in $$t\bar{t} \to \mu$$ + jet events produced by $$p\bar{p}$$ collisions with $$\sqrt{s}$$ = 1.8 TeV at the Fermilab Tevatron and observed with the D0 detector. The data set analyzed is identical to that used by the D0 Collaboration in its reported discovery of the top quark which engaged other decay channels as well.1 Four events are observed with an expected background of 1.40 $$\pm$$ 0.71 events. The probability for an upward fluctuation of the background to produce the observed number of events is 0.081 (equivalent to 1.7 standard deviations). An analysis for the top quark mass is carried out based on the amount of jet activity transverse to the $$p\bar{p}$$ beam direction. The resultant top quark mass value is measured to be $$185^{+16}_ {-26}$$(stat.)$$^{+6}_ {-8}$$(syst.) GeV/$c^2$ with a corresponding production cross section of 5.3 $$\pm$$ 4.4 pb.
