Description

Planned collider experiments will decisively test the color SU(5) model of Foot and Hernandez, in which an extended QCD group is broken at the TeV scale. Constraints from cosmology and from neutral-kaon mixing imply that exotic charge-1/2 fermions of this model cannot all be given masses above about 1 TeV. These ''quirks'' carry a new strong confining force, from the surviving unbroken gauge symmetry. Searches for the leptonic decay products of quirkonium at CERN LEP II will probe quirk masses up to near the beam energy, while searches at planned hadron colliders will be sensitive to quirk masses all the way up to the TeV upper bound
