Abstract
|
|
|
|
| We report the results of a search for a narrow resonance in electron-positron events in the invariant mass range of 150950 GeV/c2 using 1.3 fb-1 of pp̅ collision data at √s=1.96 TeV collected by the CDF II detector at Fermilab. No significant evidence of such a resonance is observed and we interpret the results to exclude the standard-model-like Z′ with a mass below 923 GeV/c2 and the Randall-Sundrum graviton with a mass below 807 GeV/c2 for k/M̅ pl=0.1, both at the 95% confidence level. Combining with diphoton data excludes the Randall-Sundrum graviton for masses below 889 GeV/c2 for k/M̅ pl=0.1. |
