Neutrinos: Windows to Planck Physics
P. Ramond
After recalling some elegant contributions of the late Freydoon Mansouri, we turn to neutrino physics and use a {\it modicum} of grand unification to relate quark and lepton mixing…
Correlated Hierarchy, Dirac Masses and Large Mixing Angles
Aseshkrishna Datta, Fu-Sin Ling, Pierre Ramond
We introduce a new parametrization of the MNS lepton mixing matrix which separates the hierarchical Grand Unified relations among quarks and leptons. We argue that one large angle…
Dirac's Footsteps and Supersymmetry
P. Ramond
One hundred years after its creator's birth, the Dirac equation stands as the cornerstone of XXth Century physics. But it is much more, as it carries the seeds of supersymmetry. Di…
Family Hierarchy from Symmetry Breaking
Fu-Sin Ling, Pierre Ramond
We investigate symmetry breaking patterns from replicated gauge groups which generate anomaly-free and family-dependent U(1) symmetries. We discuss the extent to which these symmet…
Exceptional Groups and Physics
Pierre Ramond
Quarks and leptons charges and interactions are derived from gauge theories associated with symmetries. Their space-time labels come from representations of the non-compact algebra…
