Abstract
A search for new particles () that decay to electron or muon pairs has been performed using approximately of collision data at collected by the CDF II experiment at the Fermilab Tevatron. Limits on are presented as a function of dilepton invariant mass , for different spin hypotheses (0, 1, or 2). The limits are approximately 25 fb for . Lower mass bounds for from representative models beyond the standard model including heavy neutral gauge bosons are presented.
