The spin-charge-family theory offers a possible explanation for the assumptions of the standard model - for the charges of a family members, for the gauge fields, for the appearance of families, for the the scalar fields - interpreting the standard model as its low energy effective manifestation. The spin-charge-family theory predicts at the low energy regime two decoupled groups of four families of quarks and leptons. The predicted fourth family waits to be observed, while the stable fifth family is the candidate to form the dark matter. The Higss and Yukawa couplings are the low energy effective manifestation of several scalar fields, all with the bosonic (adjoint) representations with respect to all the charge groups, with the family groups included. Properties of the families are analysed and relations among coherent contributions of the loop corrections to fermion properties discussed, including the one which enables the existence of the Majorana neutrinos. The appearance of several scalar fields is presented, their properties discussed, it is explained how these scalar fields can effectively be interpreted as the {\em standard model} Higgs (with the fermion kind of charges) and the Yukawa couplings, and a possible explanation why the Higgs has not yet been observed offered. The relation to proposals that the Yukawas follow from the SU(3) family (flavour) group, having the family charges in the fundamental representations of these groups, is discussed. The spin-charge-family theory predicts that there are no supersymmetric partners of the observed fermions and bosons.

The spin-charge-family theory is explaining the origin of families, of the Higgs and the Yukawa couplings

We study the connection between the dual spinor model and supersymmetry. We show that in the low-energy region, the dual spinor model yields a supersymmetric Yang-Mills theory with O(4) internal symmetry and a supergravity theory with O(4) internal symmetry.

Supersymmetry, supergravity theories and the dual spinor model

This contribution is to show how does the spin-charge-family theory interpret the assumptions of the standard model, and those extensions of this model, which are trying to see the Yukawa couplings as scalar fields with the family (flavour) charges in the fundamental representations of the group. The purpose of these contribution is i.) to try to understand why the standard model works so well, although its assumptions look quite artificial, and ii.) how do predictions of the spin-charge-family theory about the measurements of the scalar fields differ from predictions of the {\em standard model}, which has only one scalar field - the Higgs - and also from its more or less direct extensions with Yukawas as the scalar dynamical fields with the family charge in the fundamental or anti-fundamental representation of group.

How can the Standard model Higgs and also the extensions of the Higgs to Yukawa's scalars be interpreted in the spin-charge-family theory and to what predictions about the Higgs does this theory lead?

The spin-charge-family theory, proposed by the author as a possible new way to explain the assumptions of the standard model, predicts at the low energy regime two decoupled groups of four families of quarks and leptons. In two successive breaks the massless families, first the group of four and at the second break the rest four families, gain nonzero mass matrices. The families are identical with respect to the charges and spin. There are two kinds of fields in this theory, which manifest at low energies as the gauge vector and scalar fields: the fields which couple to the charges and spin, and the fields which couple to the family quantum numbers. In loop corrections to the tree level mass matrices both kinds start to contribute coherently. The fourth family of the lower group of four families is predicted to be possibly observed at the LHC and the stable of the higher four families -- the fifth family -- is the candidate to constitute the dark matter. Properties of the families of quarks and leptons and of the scalar and gauge fields, before and after each of the two successive breaks, bringing masses to fermions and to boson fields are analysed and relations among coherent contributions of the loop corrections to fermion properties discussed, including the one which enables the existence of the Majorana neutrinos. The relation of the scalar fields and mass matrices following from the {\em spin-charge-family} theory to the {\it standard model} Yukawa couplings and Higgs is discussed. Although effectively the scalar fields manifest as Higgs and Yukawas, measurements of the scalar fields do not coincide with the measurement of the Higgs.

Properties of twice four families of quarks and leptons, of scalars and gauge fields as predicted by the spin-charge-family-theory

The standard model of the elementary particles is built on several assumptions. The Higgs is assumed to be a scalar, a boson, with the charges of a fermion (in the fundamental representations of the charge groups). No explanation is offered for the existence of families of fermions -- quarks and leptons-- for the charges of these family members, for the appearance of the Yukawas which take care of fermion properties. The theory explaining the origin of families predicts that several scalar fields with the boson kind of the charges (in the adjoint representations of the charge groups) manifest effectively at low energies as the Higgs and the Yukawas.
