Measurement of the T $\bar{t}$ Cross-Section Using the Dimuon Channel in P$\bar{p}$ Collisions at {u221A}s

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.
Measurement of the T Anti-t Cross-Section Using the Dimuon Channel in P Anti-p Collisions at S**(1/2)

The author has 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.
Measurement of the T Anti-t Cross-Section Using the Dimuon Channel in Ppbar Collisions at Sqrt(s)

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.
