– The principle of “Threeality” in fundamental physics.
– The hierarchy problem for scalars, supersymmetry?
– Grand unification, p-decay?
– Neutrino Mass, mixing, CPV, majorana?
– Charged lepton flavour violation?
– Baryon asymmetry of the Universe
– Dark matter
– Dark energy
Most ideas tackling these points are linked to the Minkowski spacetime paradigm
that symmetries will continue to be the guiding principle for fundamental physics.
Among the discrete symmetries, CPT is protected by the “CPT-Theorem” in quantum field theory formulated in with interactions satisfying Lorentz invariance,
locality and unitarity. But there is nothing at the level of quantum mechanics
which forbids to have CPT-violation and there are sound quantum gravity arguments
in favour of this ultimate symmetry breaking.
