A Constrained Standard Model from a Compact Extra Dimension
Riccardo Barbieri, Lawrence J. Hall, Yasunori Nomura
A SU(3) \times SU(2) \times U(1) supersymmetric theory is constructed with a TeV sized extra dimension compactified on the orbifold S^1/(Z_2 \times Z_2'). The compactification brea…
Non standard analysis of the solar neutrino anomaly (updated including the SNO day/night spectral data)
Riccardo Barbieri, Alessandro Strumia
Continuing previous work, a model independent analysis of the solar neutrino anomaly is performed in terms of neutrino oscillations, allowing a comparison with the predictions of t…
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…
Relating m_Higgs to m_SUSY by a loop factor
Riccardo Barbieri, Alessandro Strumia
We assume that the scale of the soft supersymmetry breaking masses, m_SUSY, sliding at tree level, is fixed by the minimization of the potential, but without a significant contribu…
Neutrino oscillations and large extra dimensions
Riccardo Barbieri, Paolo Creminelli, Alessandro Strumia
Assuming that right-handed neutrinos exist and propagate in some large extra dimensions, we attempt to give a comprehensive description of the phenomenology of neutrino oscillation…
