Mass Generation from Lie Algebra Extensions
R. Aldrovandi, V. C. de Andrade, A. L. Barbosa +1
Applied to the electroweak interactions, the theory of Lie algebra extensions suggests a mechanism by which the boson masses are generated without resource to spontaneous symmetry…

Gravitomagnetic Moments of the Fundamental Fields
R. Aldrovandi, V. C. de Andrade, J. G. Pereira
The quadratic form of the Dirac equation in a Riemann spacetime yields a gravitational gyromagnetic ratio κ_S = 2 for the interaction of a Dirac spinor with curvature. A gravitatio…
