Search for New Physics Using High-Mass Tau Pairs from 1.96 TeVpp¯Collisions

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 $p\overline{p}$ collider. Such anomalous production could arise from various new physics processes. In a data sample corresponding to $195{\mathrm{pb}}^{-1}$ 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.
