A search for high-mass resonances in the e+e- final state is
presented based on s**(1/2) ñ.96 TeV p anti-p collision data from the
CDF II detector at the Fermilab Tevatron from an integrated luminosity
of 2.5 fb-1. The largest excess over the standard model prediction is at
an e+e- invariant mass of 240 GeV/c2. The probability of observing such
an excess arising from fluctuations in the standard model anywhere in the
mass range of 150-1,000 GeV/c2 is 0.6% (equivalent to 2.5 sigma). We set
Bayesian upper limits on sigma(p anti-p --> X) . B(X --> e+e-) at
the 95% credibility level, where X is a spi+n 1 or spi+n 2 particle, and
we exclude the standard model coupling Z' and the Randall-Sundrum graviton
for k/M_Pl 0.1 with masses below 963 and 848 GeV/c2, respectively.
