Textures, Family Symmetries and Neutrino Masses
Elena Papageorgiu
We review recent work on the interplay between broken family symmetries which give rise to approximate texture zeros in the mass matrices of the quarks and leptons and the presence…
Generating the texture of symmetric fermion mass matrices and anomalous hierarchy patterns for the neutrinos from an extra abelian symmetry
E. Papageorgiu
Assuming that a horizontal abelian (gauge) symmetry is at the origin of texture zeros in the fermion mass matrices we show how realistic mass patterns can be generated stepwise wit…
Searching for An Intermediate-Mass Higgs and New Physics in Two-Photon Coherent Processes at the LHC
Elena Papageorgiu
We reexamine the prospects for searching for a neutral Higgs boson in the intermediate-mass range and physics beyond the standard model, using the proton- and ion-beam facilities o…
Fermion masses and mixing from an extra gauge symmetry
Elena Papageorgiu
Assuming that a horizontal abelian (gauge) symmetry is at the origin of texture zeros in the fermion mass matrices we show how realistic mass patterns can be generated in the prese…
Symmetries at ultrahigh energies and searches for neutrino oscillations
E. Papageorgiu
Motivated by the possibility that new (gauge) symmetries which are broken at the grand- (string-) unification scale give rise to texture zeros in the fermion mass matrices which ar…
An intermediate-mass Higgs boson in two-photon coherent processes at the LHC
E. Papageorgiu
We reexamine the prospects of searching for a neutral Higgs boson in the intermediate-mass range, using the proton- and ion-beam facilities of the LHC to study coherent two-photon…
Yukawa textures from an extra {\bf U(1)} symmetry?
E. Papageorgiu
The observed hierarchy of the quark and lepton masses and mixing angles has led to the parametrisation of the mass matrices in powers of the Cabibbo angle and a certain number of z…
Neutrino properties from maximally-predictive GUT models and the structure of the heavy Majorana sector
E. Papageorgiu
Starting from a complete set of possible parametrisations of the quark-mass matrices that have the maximum number of texture zeros at the grand unification scale, and the Georgi-Ja…
