Low Energy Thresholds and the Scalar Mass Spectrum in Minimal Supersymmetry
G. K. Leontaris, N. D. Tracas
We discuss low energy threshold effects and calculate the sparticle masses in the context of the Minimal Supersymmetric Standard Model. We pay particular attention to the top squar…
Neutrino Masses from Gauge Symmetries
H. Dreiner, G. K. Leontaris, S. Lola +2
A very simple extension of the standard model to include an Abelian family symmetry is able to describe the hierarchy of quark and lepton masses and their mixing angles together wi…
Large Top and Bottom Yukawa Couplings in Minimal Supersymmetry
E. G. Floratos, G. K. Leontaris
We present analytic expressions for the top and bottom Yukawa couplings in the context of the minimal supersymmetric standard model when both couplings are large…
A New Treatment of Neutrino Oscillations in Medium
G. K. Leontaris, J. D. Vergados
A new more rigorous and accurate method for treating neutrino oscillations in the context of the MSW effect in a medium is proposed. This leads to a new type of resonance condition…
Implications of a Heavy Top in Supersymmetric Theories
G. K. Leontaris, N. D. Tracas
In the context of the radiative electroweak symmetry breaking scenario, we investigate the implications of a heavy top quark mass, close to its infrared fixed point, on the low ene…
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…
