Phenomenology of iQuarkonium

Phenomenology of uncolored iquarks - hypothetical fermions charged under a new confining unbroken non-abelian gauge group as well as the standard electroweak gauge group - is investigated for the iquark mass in the range near and above 100 GeV. If the new confining scale turns out to be higher than MeV but much less than the iquark mass, the iquark-antiiquark pair produced in the collider will promptly relaxed into the ground state of the iquarkonium. Subsequent pair annihilation into standard model particles gives useful information of the iquark dynamics. We formulate in details production and decays of the iquark-antiiquark bound states. Decay patterns of the iquarkonium can be distinguished from the superheavy quarkonium of a sequential fourth generation of quarks with degenerate mass.
