On the stability of nontopological solitons in supersymmetric extensions of the Standard Model: A Numerical Approach
G. K. Leontaris, A. Prikas, A. Spanou +2
In various supersymmetric extensions of the Standard Model there appear non-topological solitons due to the existence of U(1) global symmetries associated with Baryon and/or Lepton…
World volume Supermembrane Instantons in the light-cone frame
E. G. Floratos, G. K. Leontaris
In this review we present the octonionic duality for membranes. We start with a discussion on the relation of the Yang Mills theories and the supermembrane Hamiltonian in the light…
Neutrino masses in supersymmetric theories
G. K. Leontaris, S. Lola
Extensions of the Standard Model with additional U(1) symmetries can describe the hierarchy of fermion masses and mixing angles, including neutrinos. The neutrino masses and mixing…
Neutrino Properties in a GUT Analysis for Fermion Masses
G. K. Leontaris, J. D. Vergados
In practically all extentions of the standard model, the neutrinos naturally acquire a mass. The neutrino mass matrix, however, contains many parameters which can neither be predic…
