The Fermion Generation Problem in the Gust’s of the Free World Sheet Fermion Formulation

“…For example in the case of N g = 3 + 1 families with Fritzsch ansatz for quark mass matrices and using SU(3) H ×SU(2) Higgs fields, (8,2), [5], we can write down some rough relations between the masses of horizontal gauge bosons ("bootstrap" solution):…”

“…The phases in this formula are redused mod (2) and are chosen to be in the interval (−1, +1]. Modular transformations mix spin-structures amongst one another within a surface of a given genus.…”

“…For rational phases α(f ) (we consider only this case) the possible boundary conditions α comprise a finite additive group Ξ = k i=1 ⊕Z N i which is generated by a basis (b 1 , · · · , b k ), where N i is the smallest integer for which N i b i = 0 mod (2). A multiplication of two vectors from Ξ is defined by…”

“…The unitarity triangle is constructed from the following unitarity condition of V CKM : V * ub + V td ≈ Aλ 3 . Recently, the interest in the CP-violation problem was excited again due to the data on the search for the direct CP-violation effects in neutral K-mesons [1], [2] :…”

“…Due to the local gauge family symmetry with a low energy breaking scale Λ H ≈ 1T eV gives us a chance to define the quantum numbers of quarks and leptons and thus establishes a link between them in families. For the mass fermion ansatz considered above in the extensions of SM there could exist the following types of the SU(3) × SU(2 L ) Higgs multiplets:(1,2), (3,1), (8,1), (3,2), (8,2),(1,1),...., which in turn could exist in the spectra of the String Models.…”
