摘要

The ''theoretical'' arguments for the uniqueness of the standard color-flavor gauge group are reexamined. It is pointed out that SU(3) is the only ''color'' group that is consistent with the Pauli principle for three-quark flavor systems (baryons) and does not permit fractionally charged unconfined quark-gluon objects. A new argument is produced for the left-right-symmetric electroweak group SU(2)/sub L/ x SU(2)/sub R/ x U(1)/sub S - L/ being the maximal gauged chiral flavor subgroup of the global chiral quark flavor group SU(n)/sub L/ x SU(n)/sub R/ x U(1)/sub L + R/ for n flavors of massless quarks. This explains the generational grouping in quark and lepton chiral doublets and encourages increased efforts to find the new physics in the LRS electroweak group. 8 refs. (ERA citation 13:002315)
