Search for New Physics Using High Mass Tau Pairs from 1.96-TeV Proton-Antiproton Collisions

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${}^{-1}$ of integrated luminosity we predict 2.8$\pm$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.
