Top decays in the dilepton channel at CDF

PDF Version Also Available for Download.

Description

The author presents an observation of t{anti t} production in the dilepton decay channel using the CDF detector at the Fermilab Tevatron Collider. This measurement was made using {approx} 67 pb{sup {minus}1} of data, 19.3 of which was taken during the 1992--93 data run while the remaining data has been acquired this past year (94--95). He observed 6 events in the t{anti t} signal region with an expected background of 1.3 {+-} 0.3 events. This signal is inconsistent with the background prediction by 2.7{sigma}. Additionally, three of these events contain a total of 5 b-tags--strong evidence for WWb production. He ... continued below

He measured the t{anti t} production cross section in the dilepton channel to be {sigma}{sub t{anti t}} = 10.9{sub {minus}4.5}{sup +5.9}pb.
