Abstract
|
|
|
|
| We report the results of a search for the anomalous production of a massive particle decaying to four electrons via two Z0 bosons in 1.1 fb-1 of pp̅ collisions at √s=1.96 TeV collected by the CDF II detector at Fermilab. We employ optimized electron identification criteria to maximize acceptance and efficiency. We estimate the backgrounds in the invariant mass range 5001000 GeV/c2 to be 0.028±0.009(stat)±0.011(syst) events. We observe zero events in this search region. Assuming a Randall-Sundrum graviton production model, we set 95% C.L. limits on σ×BF(G→Z0Z0)<46 pb, depending on the graviton mass. |
