Measurement of event shapes in <em>pp</em> collisions at √s=1.96  TeV

between various predictions is shown in Figs.. The s k,t is the shift in the kth systematic for the t theoretical prediction. The first term represents the un- correlated scatter of

‘‘beam-beam remnants.’’ Also, for PYTHIA the ‘‘beam-beam remnants’’ include contributions from multiple parton scat- tering as illustrated in Fig. Figure 33 and Fig.

In this paper, we test this assumption by measuring the ambient charged track momentum in events containing large transverse energy jets at s√=1800  GeV and s√=630  GeV

The measured cross sections are determined for the full W decay phase space, transverse mass range, and photon range using extrapolations based upon the SM expectation [19].

We estimate the background contribution from W events with only light-flavor jets by applying the mistag rate, measured in the inclusive jet data set and parametrized in jet E T , ,

In the case of electrons misidentified as tau candidates, false 0 reconstruction can overestimate the hadronic tau candidate energy by up to a factor of 2, since the candidate

Two data sets are used for this measurement: a sample of jets from inclusive jet production, containing only a negligible amount of b -jets, and a sample where the heavy-flavor
