# Search for new physics in high mass electron-positron events in $p \bar{p}$ collisions at $\sqrt{s}$ = 1.96-TeV

We report the results of a search for a narrow resonance in electron-positron events in the invariant mass range of 150--950 GeV/c2 using 1.3 fb-1 of p[overline p] collision data at sqrt(s)=1.96 TeV collected by the CDF II detector at Fermilab. No significant evidence of such a resonance is observed and we interpret the results to exclude the standard-model-like Z[prime] with a mass below 923 GeV/c2 and the Randall-Sundrum graviton with a mass below 807 GeV/c2 for k/[overline M]pl=0.1, both at the 95\% confidence level. Combining with diphoton data excludes the Randall-Sundrum graviton for masses below 889 GeV/c2 for k/[overline M]pl=0.1.
