Symmetry breaking and photon–neutrino interaction absence

Determine whether the basis-vector description offers a simpler explanation of the symmetry breaking from SO(13,1) to SO(3,1) × U(1) × SU(3), and establish whether the resultant symmetry-breaking pattern explains why photons interact with quarks and charged leptons and their antiparticles but not with neutrinos.

Background

The theory embeds the Standard Model gauge groups within SO(13,1), with observed physics arising after a sequence of symmetry breakings. The authors ask whether their basis-vector approach clarifies this breaking and, importantly, explains the empirical absence of photon–neutrino interactions.

This question targets both formal model-building (group-theoretic breaking) and phenomenological consequences (interaction selection rules) within the proposed framework.

There remain questions to be answered: iv.c. Does this way of describing the internal spaces of fermion and boson fields offer easier explanation for breaking symmetries from SO(13,1) to SO(3,1)× U(1) ×SU(3)? Can the breaks of symmetries explain why photons interact with all quarks and charged leptons and antiquarks and charged antileptons but not with neutrinos?
