Search for High-Mass e+e- Resonances in pp-bar Collisions at sqrt[s]=1.96 TeV

A search for high-mass resonances in the e[superscript +]e[superscript -] final state is presented based on 2.5  fb[superscript -1] of √s=1.96  TeV pp̅ collision data from the CDF II detector at the Fermilab Tevatron. The largest excess over the standard model prediction is at an e[superscript +]e[s...

520 |a A search for high-mass resonances in the e[superscript +]e[superscript -] final state is presented based on 2.5  fb[superscript -1] of √s=1.96  TeV pp̅ collision data from the CDF II detector at the Fermilab Tevatron. The largest excess over the standard model prediction is at an e[superscript +]e[superscript -] invariant mass of 240  GeV/c[superscript 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[superscript 2] is 0.6% (equivalent to 2.5σ). We exclude the standard model coupling Z' and the Randall-Sundrum graviton for k/M̅ Pl=0.1 with masses below 963 and 848  GeV/c[superscript 2] at the 95% credibility level, respectively.
