Abstract

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