Their topics include the zeta-regularized stress-energy vacuum expectation value in terms of integral kernels, total energy and forces on the boundary, a massless field between parallel hyperplanes, a massive field constrained by perpendicular hyperplanes, and a scalar field with a harmonic background potential.
This allows electrons in the bulk of the crystal to behave as though they were massless particles, effectively a bulk analogue of the atomically-thin material graphene.
That combination produces a neutron--thus giving this new star its name--as well as nearly massless, ghostly particles called neutrinos that rapidly escape from the star, carrying with them a large amount of energy.
According to [9], the <<Higgs>> mechanism for relativistic theories of the interaction of elementary particles is based on the idea that when a massless scalar particle <<contacts>> a massless carrier of interaction, a carrier particle with mass (some unknown massive boson) is born.
Physicists say that if a special kind of radioactive decay called "neutrinoless double-beta decay" is observed, it would prove two things - one, that in certain circumstances more matter is in fact created than antimatter; and two, neutrinos (which are virtually massless particles produced during radioactive decay) can behave as their own antiparticles.
It means that massless elementary electrical charges (MEECs), everywhere, incorporate the local space-time evolution of the incoming zero-point radiation (ZPR).
Two well-known assumptions (inelastic and massless assumptions) were plotted.
This linear dispersion can be mapped onto the Dirac- or Weyl-Hamiltonian, describing relativistic massless fermions, and thus relativistic phenomena from high-energy physics may appear in these materials.
It was in 2013 he got the Nobel prize for physics which he shared with Francois Englert of the Free University of Brussels who had independently come up with a model explaining why particles are not massless and this model requires the existence of the Higgs boson.

Abstract: Silicene is a monolayer allotrope of silicon atoms arranged in a honeycomb structure with massless Dirac fermion characteristics similar to graphene.
In this speculative work dealing with mind and quantum field theory, I subscribe to the notion that elementary fermions (spin-1/2 particles) are massless fields that generate luxons (particles that travel at lightspeed and hence do not experience spacetime) until they interact with the Higgs field whereby through the Feynman Penrose zig-zag picture they acquire both real and imaginary mass.
