Search for anomalous kinematics in t anti-t dilepton events at CDF II
Description
We report on a search for anomalous kinematics of t(bar t) dilepton events in p(bar p) collisions at √s = 1.96 TeV using 193 pb-1 of data collected with the CDF II detector. We developed a new a priori technique designed to isolate the subset in a data sample revealing the largest deviation from standard model (SM) expectations and to quantify the significance of this departure. In the four-variable space considered, no particular subset shows a significant discrepancy and we find that the probability of obtaining a data sample less consistent with the SM than what is observed is 1.0-4.5%
