A SIMPLE SOLUTION FOR THE FLAVOR QUESTION

We consider a simple way of solving the flavor question by embedding t he three-family standard model in a semisimple gauge group extending m inimally the weak isospin factor. Quantum chiral anomalies between fam ilies of fermions cancel with a matching of the number of families and the number of color degrees of freedom. Our demonstration shows how t he theory leads to determination of families structure when the standa rd model is the input at low energies. The new physics is limited to s tart below a few TeVs within the reach of the next generation collider s.
