Do we have the explanation for the Higgs and Yukawa couplings of the standard model?

TL;DR

The paper discusses the spin-charge-family theory as a potential explanation for the Higgs and Yukawa couplings, predicting new scalar fields that could lead to observable differences from the standard model at the LHC.

Contribution

It introduces the spin-charge-family theory as an extension of the standard model, predicting scalar fields with specific properties affecting fermion and boson masses.

Findings

Scalar fields manifest as doublets and triplets with respect to different quantum numbers

Predictions for LHC may differ from the standard model due to scalar field differences

Provides a theoretical framework linking scalar fields to fermion and boson mass generation

Abstract

The spin-charge-family theory offers a possible explanation for the assumptions of the standard model, interpreting the standard model as its low energy effective manifestation. The theory predicts several scalar fields determining masses and mixing matrices of fermions and weak bosons. The scalar fields manifest as doublets with respect to the weak charge, while they are triplets with respect to the family quantum numbers. Since free scalar fields (mass eigen states) differ from those which couple to $Z_m$ and to $W^{\pm}_{m}$ or to each family member of each of the family the spin-charge-family theory predictions for LHC might differ from those of the standard model.
