Mirror World at the Large Hadron Collider
Riccardo Barbieri, Thomas Gregoire, Lawrence J. Hall
A mirror world can modify in a striking way the LHC signals of the Higgs sector. An exact or approximate Z_2 symmetry between the mirror world and our world allows large mixing bet…
ElectroWeak Symmetry Breaking as of 2003, on the way to the Large Hadron Collider
Riccardo Barbieri
I review the status of the ElectroWeak Symmetry Breaking problem. The lectures are naturally divided into two parts. The first is mostly devoted to overview the impact of current d…
A Constrained Standard Model: Effects of Fayet-Iliopoulos Terms
Riccardo Barbieri, Lawrence J. Hall, Yasunori Nomura
In hep-ph/0011311 the one Higgs doublet standard model was obtained by an orbifold projection of a 5D supersymmetric theory in an essentially unique way, resulting in a prediction…
The `LEP paradox'
Riccardo Barbieri, Alessandro Strumia
Is there a Higgs? Where is it? Is supersymmetry there? Where is it? By discussing these questions, we call attention to the `LEP paradox', which is how we see the naturalness probl…
Atmospheric and Solar neutrinos in the light of the SuperKamiokande results
Riccardo Barbieri
The hierarchy and the large mixing angle, as suggested by neutrino oscillation experiments, can be accounted for by a variety of lepton flavour…
A Grand Unified Supersymmetric Theory of Flavor
Riccardo Barbieri, Lawrence Hall
A grand unified theory is constructed with a hierarchical breaking of a flavor symmetry. The small parameters of the squark and slepton mass matrices, necessary to s…
