F-flatness and universality in broken Supergravity
Oscar Vives
We show that in a broken supergravity theory any field that acquires a vacuum expectation value obtains at the same time a non vanishing F-term whose natural size is given by $<θ>…
Yukawa structure, flavour and CP violation in Supergravity
G. G. Ross, O. Vives
The hierarchical structure of fermion masses and mixings strongly suggests an underlying family symmetry. In supergravity any familon field spontaneously breaking this symmetry nec…
Seesaw and Lepton Flavour Violation in SUSY SO(10)
Antonio Masiero, Sudhir K. Vempati, Oscar Vives
That and are sensitive probes of SUSY models with a see-saw mechanism is a well accepted fact. Here we propose a `top-down' approach in a general SUSY SO(10)…
CP violation in realistic String Models with family universal anomalous U(1)
Alon E. Faraggi, Oscar Vives
The characteristic property of the Z2XZ2 orbifold compactification is the cyclic permutation symmetry between the three twisted sectors. We discuss how this property, which is reta…
