Multimuon signals at the Superconducting Super Collider from heavy quarks

An analysis is presented of the cross section at Superconducting Super Collider energies for events containing a large number of muons, arising from the production and decay of t quarks and of fourth-generation quark-antiquark pairs. We find that for fourth-generation masses in the range 140≤$m_Q$≤240 GeV, events containing six muons (of both signs) or four same-sign muons, with realistic momentum and rapidity cuts, will be detectable in the 0.1–1.0-pb range with essentially zero background from t-quark production or other sources.
