Book Description
The author has measured the t$ar{t}$ production cross section at √s = 1.96 TeV using data collected by the D0 experiment at Fermilab. The integrated luminosity of the data set is 140 pb-1 and a total of four candidate events are seen, with an expected background of 2.61 events. The measured cross section of ?t$ar{t}$ = 11.1$+22.1top{-9.3}$(stat.)$+4.3top{-4.5}$(sys.) pb is in agreement with a NNLO calculation of 6.77 pb.

Book Description
The authors have measured the t[bar t] production cross section at [radical]s = 1.96 TeV using data collected by the D0 experiment at Fermilab. The integrated luminosity of the data set is 140 pb[sup -1] and a total of four candidate events are seen, with an expected background of 2.61 events. The measured cross section of [sigma][sub t[bar t]] = 11.1[sub -9.3][sup +22.1](stat.)[sub -4.5][sup +4.3](sys.) pb is in agreement with a NNLO calculation of 6.77 pb.

Book Description
I present a measurement of the t$ar{t}$ production cross section at √s = 1.96 TeV using 2034 pb-1 of CDF Run II data using events with a high transverse momentum electron or muon, three or more jets, and missing transverse energy. The measurement assumes a t → Wb branching fraction of 100 percent. Events consistent with t$ar{t}$ decay are found by identifying jets containing heavy-flavor semileptonic decays to muons. The dominant backgrounds are evaluated directly from the data. Based on 248 candidate events and an expected background of 86.8 ± 5.6 events, I measure a production cross section of 8.7 ± 1.1$+0.9top{-0.8}$ ± 0.6 pb, in agreement with the Standard Model.

Book Description
Measurements of differential cross sections for J/[psi] production in p + Pb collisions at [arrow]"NN=5.02 TeV at the CERN Large Hadron Collider with the ATLAS detector are presented. The data set used corresponds to an integrated luminosity of 28.1 nb-1. The J/[psi] mesons are reconstructed in the dimuon decay channel over the transverse momentum range 8
