  There are suggestive experimental indications that the leptons, neutrinos,
and quarks are composite and that their structure is described by the quantum
group SLq(2). Since the hypothetical preons must be very heavy relative to the
masses of the leptons, neutrinos, and quarks, there must be a very strong
binding field to permit these composite particles to form. Unfortunately there
are no experiments direct enough to establish the order of magnitude needed to
make the SLq(2) Lagrangian dynamics quantitative. It is possible, however, to
parametrize the preon masses and interactions that would be necessary to
stabilize the three particle composite representing the leptons, neutrinos, and
quarks. In this note we examine possible parametrizations of the masses and the
interactions of these hypothetical structures. We also note an alternative view
of SLq(2) preons.
