Results on CP violation from CDF

Description: The CDF experiment at the Tevatron collider is collecting a large sample of fully hadronic decays of Bottom and Charm mesons. First CP Violation measurements have been performed using the initial data, achieving results which clearly state the CDF ability in extracting significant CKM information from p{bar p} collisions. The first results on direct CP asymmetries on Charm and Bottom decays and future plans from the CDF experiment are discussed in this paper.

Exotic physics: search for new physics leading to high mass tau pairs with ppbar collisions at 1.96 tev using cdf ii

Description: Abstract: We present the results of a search for anomalous resonant production of tau lepton pairs with large invariant mass, the first such search using the CDF II Detector in Run II of the Tevatron p{bar p} collider. Such anomalous production could arise from various new physics processes. In a data sample corresponding to 195 pb{sup -1} of integrated luminosity we predict 2.8 {+-} 0.5 events from Standard Model background processes and observe 4. We use this result to set limits on the production of heavy scalar and vector particles decaying to tau lepton pairs.
