Search for Anomalous Kinematics in ttbar Dilepton Events at CDF II
CDF collaboration, D. Acosta
Abstract
We report on a search for anomalous kinematics of ttbar dilepton events in ppbar collisions at sqrts=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%.
