Abstract
We report the results of a search for a narrow resonance in electron-positron events in the invariant mass range of using of collision data at 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 with a mass below and the Randall-Sundrum graviton with a mass below for , both at the 95% confidence level. Combining with diphoton data excludes the Randall-Sundrum graviton for masses below for .
