Gauge Coupling Unification and the Top Mass in String Models with Symmetry
G. K. Leontaris, N. D. Tracas
We discuss the low energy implications of gauge coupling unification at the string scale, taking into account string threshold corrections in the model. We ex…
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…
Textures for Neutrino Mass Matrices
G. K. Leontaris, S. Lola, C. Scheich +1
We give a classification of heavy Majorana neutrino mass matrices with up to three texture zeroes, assuming the Dirac masses of the neutrinos to be of the same form as the ones of…
MSSM phenomenology in the large tanb regime
E. G. Floratos, G. K. Leontaris, S. Lola
We discuss aspects of the low energy phenomenology of the MSSM, in the large regime. We explore the regions of the parameter space where the and Yukawa coupli…
Heavy neutrino threshold effects in low energy phenomenology
G. K. Leontaris, S. Lola, G. G. Ross
Right handed neutrinos with mass of GeV are required to implement the see-saw mechanism and generate neutrino masses capable of playing a role in st…
Analytic Approach to the MSSM Mass Spectrum in the Large Tan Regime
E. G. Floratos, G. K. Leontaris
In various unified extensions of the Minimal Supersymmetric Standard Model, the Yukawa couplings of the third generation are predicted to be of the same order. As a result, low ene…
