Аннотация:
Quarks cannot propagate outside the nucleons or mesons, but inside they seem
to behave at high energies as almost free particles. An alternative approach
to color dynamics is proposed. It is based on the observation that the
$Z_2 \times Z_3 = Z_6$ cyclic group generated by the sixth root of unity can be put
into one-to-one correspondence with three colors and three anti-colors.
If we identify 0 as "colorless", or "white", there are two ternary and three
binary combinations of roots yielding zero. Combining spin with color,
and including particle-antiparticle symmetry, we arrive at 12-component
objects, satisfying generalized Dirac equation whose solutions cannot
propagate alone due to the complex wave vectors, but can form propagating
combinations via ternary or binary products.
Relativistic invariance implemented via non-standard complex realizations
of the Lorentz group is also discussed.
