Abstract
A search for high-mass resonances in the e+e- final state is presented based on 2.5fb-1 of s=1.96TeV pp̄ 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 240GeV/c2. The probability of observing such an excess arising from fluctuations in the standard model anywhere in the mass range of 150-1000GeV/c2 is 0.6% (equivalent to 2.5σ). We exclude the standard model coupling Z′ and the Randall-Sundrum graviton for k/M̄Pl=0.1 with masses below 963 and 848GeV/c2 at the 95% credibility level, respectively. © 2009 The American Physical Society.
