Metacolor

Abstract

A new mechanism is presented for the generation of quark and lepton masses, based on a heavy fourth family and a new sector of massless fermions. The massless fermions have only discrete chiral symmetries and they are confined by the metacolor force. The resulting electroweak corrections may be smaller than in technicolor theories.
