TLDR
In this paper, it was shown that all masses and couplings of the two Higgs bosons, in particular those of the lightest one, are determined by low energy considerations.Abstract:
We continue investigating the Standard Model for one generation of fermions and two parity-transformed Higgs doublets K and H advocated for in a previous work, using the one-to-one correspondence, demonstrated there, between their components and bilinear quark operators. We show that all masses and couplings, in particular those of the two Higgs bosons $\varsigma$ and $\xi$, are determined by low energy considerations. The mass of the ''quasi-standard'' Higgs boson, $\xi$, is $m_\xi \approx m_\pi$; it is coupled to u and d quarks with identical strengths. The mass of the lightest one, $\varsigma$, is $m_\varsigma \approx m_\pi \frac{f_\pi}{2\sqrt{2}m_W/g} \approx\ 34\,KeV$; it is very weakly coupled to matter except hadronic matter. The ratio of the two Higgs masses is that of the two scales involved in the problem, the weak scale $\sigma=\frac{2\sqrt{2}m_W}{g}$ and the chiral scale $v=f_\pi$, which are also the respective vacuum expectation values of the two Higgs bosons. They can freely coexist and be accounted for. The dependence of $m_\varsigma$ and $m_\xi$ on $m_\pi$, that is, on quark masses, suggests their evolution when more generations are added. Fermions get their masses from both Higgs multiplets. The theory definitely stays in the perturbative regime.read more

Unlocking the Standard Model. III. 2 Generations of quarks : calculating the Cabibbo angle
TL;DR: In this paper, the Cabibbo angle is given by tan^2(theta_c) = ( 1/m_K^2-1/m-D^2)/( 1/ m_\pi^2 -1/ m_{D_s}^2) \approx (m_π^2 /m_ K^2)(1-m_k^2/m/D^ 2 + m_π+m

Unlocking the Standard Model. IV. N=1 AND 2 generations of quarks : spectrum and mixing
TL;DR: In this article, the Glashow-Salam-Weinberg model for 2 generations is extended, without adding any extra fermion, to 8 composite Higgs multiplets using a one-to-one correspondence between its complex Higgs doublet and very specific quadruplets of bilinear quark operators.

Partial Symmetries of Weak Interactions
TL;DR: In this paper, the weak and electromagnetic interactions of leptons are examined under the hypothesis that the weak interactions are mediated by vector bosons, and it is shown that the simplest partially-symmetric model reproducing the observed electromagnetic and weak interactions requires the existence of at least four vector-boson fields (including the photon).

TL;DR: In this article, theoretical and phenomenological aspects of two-Higgs-doublet extensions of the Standard Model are discussed and a careful study of spontaneous CP violation is presented, including an analysis of the conditions which have to be satisfied in order for a vacuum to violate CP.

TL;DR: In this paper, the predicted ratio I.m.eq.m y/V V V was obtained from the p-dominance model, which is slightly larger than that (0.23%) obtained from Ref. 2.
