Wilson Lines and Symmetry Breaking on Orbifolds

Lawrence J. Hall, Hitoshi Murayama, Yasunori Nomura

Gauge symmetry breaking by boundary conditions on a manifold is known to be equivalent to Wilson-line breaking through a background gauge field, and is therefore spontaneous. These…

Small Neutrino Masses from Supersymmetry Breaking

Nima Arkani-Hamed, Lawrence Hall, Hitoshi Murayama +2

An alternative to the conventional see-saw mechanism is proposed to explain the origin of small neutrino masses in supersymmetric theories. The masses and couplings of the right-ha…

Sneutrino Cold Dark Matter With Lepton-Number Violation

Lawrence J. Hall, Takeo Moroi, Hitoshi Murayama

The tau sneutrino is proposed as a candidate for galactic halo dark matter, and as the cold dark matter (CDM) component of the universe. A lepton-number-violating sneutrino mass, \…

A Supersymmetric Theory of Flavor and R Parity

Christopher D. Carone, Lawrence J. Hall, Hitoshi Murayama

We construct a renormalizable, supersymmetric theory of flavor and parity based on the discrete flavor group . The model can account for all the masses and mixing angl…

A Supersymmetric Theory of Flavor with Radiative Fermion Masses

Nima Arkani-Hamed, Hsin-Chia Cheng, L. J. Hall

Supersymmetric theories involving a spontaneously broken flavor symmetry can lead to fermion masses which vanish at tree level but are generated by radiative corrections. In the co…

flavor symmetry and

Christopher D. Carone, Lawrence J. Hall, Hitoshi Murayama

We show how to incorporate the lepton sector in a supersymmetric theory of flavor based on the discrete flavor group . Assuming that all possible nonrenormalizable operato…
