Ow. Greenberg et Rc. Hilborn, Quon statistics for composite systems and a limit on the violation of the Pauli principle for nucleons and quarks, PHYS REV L, 83(22), 1999, pp. 4460-4463
The quon algebra describes particles, "quons," that are neither fermions no
r bosons. The parameter q attached to a quon labels a smooth interpolation
between bosons (q = +1) and fermions (q = -1). Wigner and Ehrenfest and Opp
enheimer showed that a composite system of identical bosons and fermions is
a fermion if it contains an odd number of fermions and is a boson otherwis
e. We generalize this and show that q(composite) = q(constituent)(n2) for a
system of rr identical quons. Using this generalization, we find bounds on
possible violations of the Pauli exclusion principle for nucleons and quar
ks based on such bounds for nuclei.
