Search for new gauge bosons decaying into dileptons in (p)over-bar-p collisions at root s=1.8 TeV

Search for new gauge bosons decaying into dileptons in (p)over-bar-p collisions at root s=1.8 TeV

We have searched for heavy neutral gauge bosons (Z′) in dielectron and dimuon decay modes using 110 pb-1 of p̄ p collisions at √s = 1.8 TeV collected with the Collider Detector at Fermilab. We present a limit on the production cross section times branching ratio of a Z′ boson decaying into dileptons...

Sammanfattning:We have searched for heavy neutral gauge bosons (Z′) in dielectron and dimuon decay modes using 110 pb-1 of p̄ p collisions at √s = 1.8 TeV collected with the Collider Detector at Fermilab. We present a limit on the production cross section times branching ratio of a Z′ boson decaying into dileptons as a function of Z′ mass. For mass MZ′ > 600 GeV/c2, the upper limit is 40 fb at 95% confidence level. We set the lower mass limits of 690, 590, 620, 595, 565, 630, and 600 GeV/c2 for Z′SM, Zψ; Zη Zχ, ZI, ZLR, and ZALRM, respectively.
