V. Desabbata et C. Sivaram, TORSION, STRING TENSION, AND TOPOLOGICAL ORIGIN OF CHARGE AND MASS, Foundations of physics letters, 8(4), 1995, pp. 375-380
We consider the analogy between torsion line defects and vortex lines
in a superconductor to suggest that the electric charge and masses of
elementary particles may have a geometrical origin. Just as the field
vanishes everywhere in a superconductor except along the vortex line,
where the flux is confined, we have the torsion being concentrated onl
y along the topological defects, giving rise to charge as well as mass
. The mass is related to the string tension (proportional to c(2)/G) a
nd charge is connected with the gravitational permeability (proportion
al to G/c(2)), both induced by torsion.
