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, \…
Tevatron Signatures of Long-lived Charged Sleptons in Gauge-Mediated Supersymmetry Breaking Models
Jonathan L. Feng, Takeo Moroi
In supersymmetric models with gauge-mediated supersymmetry breaking, charged sleptons are the next lightest supersymmetric particles and decay outside the detector for large region…
Third Generation Familons, B Factories, and Neutrino Cosmology
Jonathan L. Feng, Takeo Moroi, Hitoshi Murayama +1
We study the physics of spontaneously broken family symmetries acting on the third generation. Massless familons (or Majorons) associated with such broken symmetries are motiva…
Determining at the NLC with SUSY Higgs Bosons
Jonathan L. Feng, Takeo Moroi
We examine the prospects for determining from heavy Higgs scalar production in the minimal supersymmetric standard model at a future collider. Our analysis is inde…
New Mechanism of Flavor Symmetry Breaking from Supersymmetric Strong Dynamics
Christopher D. Carone, Lawrence J. Hall, Takeo Moroi
We present a class of supersymmetric models in which flavor symmetries are broken dynamically, by a set of composite flavon fields. The strong dynamics that is responsible for conf…
