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...

| description | 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. |
