Title: Search for New High-Mass Particles Decaying to Lepton Pairs in pp Collisions at {radical}(s)=1.96 TeV

Abstract

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