Composite fermion particles and Fisher information

Consider a composite particle consisting of quarks and antiquarks, or of electrons and positrons. The principle that the acquired Fisher information in a space-time measurement of the particle should equal its intrinsic (or maximal) level, is shown to imply that quarks q and antiquarks overlineq can exist as (1) free particles; or as (2) composite particles (hadrons) in combinations [(2l+1)q] ^m(q overlineq) ⁿ, l=1,2,...; m=0,1,2,...; n=0,1,2,.... Like combinations (1) and (2) are also predicted for electrons e and positrons overlinee under the substitutions q→ e, overlineq→ overlinee. The prediction of free quarks (1) has only recently been confirmed experimentally. Composite electron ‘clumps’ and ‘composite fermions’ have also been confirmed, although not as specifically defined by combinations (2). The quark combinations (2) are wider in scope than by the standard model of elementary particles, coinciding with the latter only for the case l=1 of 2 l+1=3 ‘colors’.
