Possible origin of a natural conservation of flavor in an interaction with neutral Higgs bosons
Ural'tsev N. G.
In technicolor models the masses of the neutral pseudo-Goldstone bosons which interact with quarks and leptons without flavor conservation automatically acquire an order of magnitude M~[mq Л TC)1/2~ 0.2-1 TeV through the Yukawa interaction. As a result, an effective Lagrangian which conserves only light Higgs bosons satisfies the condition of natural flavor conservation.
