Abstract

A search for new particles (X) that decay to electron or muon pairs has been performed using approximately 200pb-1 of pp̄ collision data at s=1.96TeV collected by the CDF II experiment at the Fermilab Tevatron. Limits on σ(pp̄→X)BR(X→) are presented as a function of dilepton invariant mass m>150GeV/c2, for different spin hypotheses (0, 1, or 2). The limits are approximately 25 fb for m>600GeV/c2. Lower mass bounds for X from representative models beyond the standard model including heavy neutral gauge bosons are presented
