Electroweak SU(2)(L) x U(1)(Y) model with strong spontaneously fermion-mass-generating gauge dynamics
Result description
Higgs sector of the Standard model (SM) is replaced by quantum flavor dynamics (QFD), the gauged flavor SU(3)(f) symmetry with scale Lambda. Anomaly freedom requires addition of three nu (R). The approximate QFD Schwinger-Dyson equation for the Euclidean infrared fermion self-energies Sigma (f)(p(2)) has the spontaneous-chiral-symmetry-breaking solutions ideal for seesaw: (1) Sigma (f)(p(2)) = MfR2/p where three Majorana masses M-fR of nu (fR) are of order Lambda. (2) Sigma (f)(p(2)) = mf2/p where three Dirac masses m(f) = m((0))1 + m((3))lambda (3) + m((8))lambda (8) of SM fermions are exponentially suppressed w.r.t. Lambda, and degenerate for all SM fermions in f. (1) M-fR break SU(3)(f) symmetry completely, m((3)), m((8)) superimpose the tiny breaking to U(1) x U(1). All flavor gluons thus acquire self-consistently the masses similar to Lambda. (2) All m(f) break the electroweak SU(2)(L) x U(1)(Y) to U(1)(em). Symmetry partners of the composite Nambu-Goldstone bosons are the genuine Higgs particles: (1) three nu (R)-composed Higgses chi (i) with masses similar to Lambda. (2) Two new SM-fermion-composed Higgses h(3), h(8) with masses similar to m((3)), m((8)), respectively. (3) The SM-like SM-fermion-composed Higgs h with mass similar to m((0)), the effective Fermi scale. Sigma (f)(p(2))-dependent vertices in the electroweak Ward-Takahashi identities imply: the axial-vector ones give rise to the W and Z masses at Fermi scale. The polar-vector ones give rise to the fermion mass splitting in f. At the present exploratory stage the splitting comes out unrealistic.
