B Candidate Details

 

This appendix lists the kinematic parameters of all lepton + jets candidate events which pass the loose cuts, plus the results of the mass fit. Each event is identified by a run and event number. The and values for the event are also listed. If the event also passes the standard cuts, the event number is followed by an asterisk (). Next, the lepton, missing , jets, and the tag muon (if present) are listed. All objects are dumped as a four vector, plus the (), , and values. Jets are R = 0.3 cone, with the out-of-cone corrections applied. Tagged jets are listed twice, both with and without the correction for the tagging muon (the latter is indicated by a dagger ()). All jets with and < 2.5 are listed, although only the first four are used for mass fitting.

Following the dump of the object four-vectors is another table giving the result of the mass fits for that event. Up to three fits are listed, giving the fitted mass (), , and the jet permutation used (the letters correspond to the first four jets; associated with leptonic top, associated with hadronic top, hadronic W). The -weighted average is also listed at the bottom. Fits with are not listed. For tagged candidates, only the fits which properly assign the tagged jet as a b are listed.

Due to an implementation error, a cut which was intended to reject before fitting jet permutations in which there was a large difference between the two top masses was actually rejecting permutations for which the smallest solution for the z-component of the neutrino momentum was large compared to the . This is noted in the few cases where this affects the results for a candidate event. Note, however, that since the procedure was applied consistently to both data and Monte Carlo, this does not affect the reliability of the final result.
