Abstract
A search for high-mass resonances in the e(+)e(-) final state is presented based on 2: 5 fb(-1) of root s = 1.96 TeV p (p) over bar collision data from the CDF II detector at the Fermilab Tevatron. The largest excess over the standard model prediction is at an e(+)e(-) invariant mass of 240 GeV/c(2). The probability of observing such an excess arising from fluctuations in the standard model anywhere in the mass range of 150-1000 GeV/c(2) is 0.6% ( equivalent to 2.5 sigma). We exclude the standard model coupling Z' and the Randall-Sundrum graviton for k/(M) over bar (P1) = 0.1 with masses below 963 and 848 GeV/c(2) at the 95% credibility level, respectively.
