Finster and Kamran propose causal fermion
systems and Riemannian fermion
systems as a framework describing non-smooth geometries, in particular, providing a setting for spinors on singular spaces.

based on Applying 8-Dimensional Spinors." DOI: 10.13140/RG.2.2.23994.90569
If one wishes to avoid exotic electric charges in the fermion
and boson sectors as the ones present in the minimal model, one must choose b = 1/2, in Eq.
But we do have the next best thing -- electrons working together in such a way that their collective behaviour produces something just like a Majorana fermion

The single-particle and collective excitations of the system under consideration manifest themselves as poles of the single-particle and two-particle Green's functions, but the corresponding expressions for the Green's functions cannot be evaluated exactly because the interaction part of the Hubbard Hamiltonian is quartic in the fermion
which is the Hamilton-Jacobi equation satisfied by a fermion
particle of mass m moving in the black hole with the electromagnetic potential [A.sub.[mu]].
where [F.sub.s] is the fermion
number operator and [[delta].sub.S] = [+ or -]1 is the space-time spin statistics index.
The monotonic decreasing behavior of the chemical potential with temperature for d/s [greater than or equal to] 1 is understood from the argument based on the fact that the internal energy U diminishes from its zero temperature value [E.sub.F] after adiabatically adding a fermion
at the small temperatures T [much less than] [T.sub.F].
The newly discovered particle, known as a Weyl fermion
, resembles a massless electron that darts around and through the material in unusual and exciting ways, physicists report online July 16 in Science.
Two new particles long thought to have existed -- the pentaquark and the Weyl fermion
, were experimentally confirmed in groundbreaking news out of MIT, Princeton, and the Large Hadron Collider (LHC).
The researchers analyzed the data gathered at the LHC between 2011 and 2012, combining the Higgs decays into bottom quarks and tau leptons, both of which belong to the fermion
particle group and the results revealed that an accumulation of these decays comes about at a Higgs particle mass near 125 gigaelectron volts (GeV) and with a significance of 3.8 sigma.
The final body chapter explores applications and analogies in other areas of science, including finite fermion
systems, astrophysical nucleation, atmospheric aerosol condensation, and medical imaging and therapy.
The physical mass is deduced by locating the pole of the fermion
propagator (i([??] + m)/([p.sup.2] - [m.sup.2] + i[epsilon])) in thermal background.
At that time a known particle with zero mass was only the Photon, a Boson, with tsh spin but he reduced mass of a fermion
or an electron in Dirac's equation and got a pair of particles with zero mass and therefore with no electric charge because if a particle has no rest mass but spin half of tsh then we are forced to assign it, zero electric charge.
