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