Kinematics of tt events at CDF Academic Article uri icon

abstract

  • The kinematic properties of tt 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 tt production are compared with those expected from Monte Carlo calculations. A sample of 34 events rich in tt 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 tt matrix element with color coherent parton shower evolution. 1999 The American Physical Society.
