Web24 de mai. de 2024 · We propose a 3+1 Higgs Doublet Model based on the ∆(27) family symmetry supplemented by several auxiliary cyclic symmetries leading to viable Yukawa textures for the Standard Model fermions, consistent with the observed pattern of fermion masses and mixings. The charged fermion mass hierarchy and the quark mixing pattern … WebThe fermions are the building blocks of matter. There are 12 fermions, split into six quarks and six leptons. Of the familiar particles that make up the atom, the electron is a lepton. However, protons and neutrons are not part of the Standard Model because they are bigger particles made out of quarks.
