Book Synopsis Search for New Heavy Particles Decaying to Z0 Z0 ---] Eeee in P - Anti-p Collisions at S**1/2 by :
Book excerpt: We report the results of a search for the anomalous production of a massive particle decaying to four electrons via two Z° bosons in 1.1 fb−1 of p{bar p} 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 500-1000 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% CL limits on [sigma] x BF(G → Z°Z°)
