Implication

Particle collision experiment finds no top-quark decay signatures in proton-antiproton collisions, indicating that top quarks must exceed 72 GeV/c² in mass.

Key Points

To search for top-quark-antiquark pair production yielding electron-muon final states within proton-antiproton collisions under the Standard Model framework.
Analyzed proton-antiproton collision data at an integrated luminosity of 4.4 pb⁻¹ using the Collider Detector at Fermilab (CDF).
Targeted the decay channel where top-antitop pairs decay into an electron, a muon, and associated particles (tt̄ → eμ + X).
Determined an experimental upper limit on the top-antitop production cross section.
Excluded Standard Model top quarks in the mass range of 28 to 72 GeV/c² at the 95% confidence level.
Ruled out fourth-generation charge -(1/3) b' quarks decaying via the charged current within the same 28 to 72 GeV/c² mass range at the 95% confidence level.
