Abstract

The kinematic properties of tt̄ events are studied in the W+ multijet channel using data collected with the CDF detector during the 1992-1995 runs at the Fermilab Tevatron collider corresponding to an integrated luminosity of 109 pb -1 . Distributions of a variety of kinematic variables chosen to be sensitive to different aspects of tt̄ production are compared with those expected from Monte Carlo calculations. A sample of 34 events rich in tt̄ pairs is obtained by requiring at least one jet identified by the silicon vertex detector (SVX) as having a displaced vertex consistent with the decay of a b hadron. The data are found to be in good agreement with predictions of the leading order tt̄ matrix element with color coherent parton shower evolution. ©1999 The American Physical Society.
