Mu-tau antisymmetry and neutrino mass matrices
Walter Grimus, Satoru Kaneko, Luis Lavoura +2
Using the seesaw mechanism and a discrete symmetry, we construct a class of models for the neutrino mass matrix where the inverse of that matrix is the sum of a mu-tau antisymmetri…
A model realizing the Harrison-Perkins-Scott lepton mixing matrix
W. Grimus, L. Lavoura
We present a supersymmetric model in which the lepton mixing matrix obeys, at the seesaw scale, the Harrison--Perkins--Scott \textit{Ansatz}--vanishing , maximal atmosp…
Is it possible to predict the sign of the Matter-Antimatter Asymmetry in the Universe?
Pavel Fileviez Perez
I investigate the possibility to define the sign of the leptonic asymmetry by the low energy parameters. It is shown that in the context of the minimal renormalizable SO(10) model…
Moduli evolution in the presence of flux compactifications
T. Barreiro, B. de Carlos, E. J. Copeland +1
We study the cosmological evolution of the volume moduli in a class of recently proposed Inflationary Universe models arising out of Type IIB string theory, where a number of the m…
S3 x Z2 model for neutrino mass matrices
W. Grimus, L. Lavoura
We propose a model for lepton mass matrices based on the seesaw mechanism, a complex scalar gauge singlet and a horizontal symmetry $S_3 \times \mathbbm{Z}_2$. In a suitable weak b…
Two predictive supersymmetric S3 x Z2 models for the quark mass matrices
Luis Lavoura, Ernest Ma
We propose two simple models for the quark mass matrices which may be implemented through an S3 x Z2 symmetry in a supersymmetric context. Each model has eight parameters and, ther…
