SU(5) D-brane realizations, Yukawa couplings and proton stability
Pascal Anastasopoulos, George K. Leontaris, Robert Richter +1
We discuss SU(5) Grand Unified Theories in the context of orientifold compactifications. Specifically, we investigate two and three D-brane stack realizations of the Georgi-Glashow…
Yukawa couplings and fermion mass structure in F-theory GUTs
G. K. Leontaris, G. G. Ross
The calculation of Yukawa couplings in F-theory GUTs is developed. The method is applied to the top and bottom Yukawa couplings in an SU(5) model of fermion masses based on family…
Gravitational Atom in Compactified Extra Dimensions
E. G. Floratos, G. K. Leontaris, N. D. Vlachos
We consider quantum mechanical effects of the modified Newtonian potential in the presence of extra compactified dimensions. We develop a method to solve the resulting Schroedinger…
Family symmetries in F-theory GUTs
S. F. King, G. K. Leontaris, G. G. Ross
We discuss F-theory SU(5) GUTs in which some or all of the quark and lepton families are assigned to different curves and family symmetry enforces a leading order rank one structur…
Phenomenological analysis of D-brane Pati-Salam vacua
P. Anastasopoulos, G. K. Leontaris, N. D. Vlachos
In the present work we perform a phenomenological analysis of the effective low energy models with Pati-Salam (PS) gauge symmetry derived in the context of D-branes. A main issue i…
