Muon colliders are expected to naturally have a small spread in beam energy making them an ideal place to study the excitation curve. We present the parameter determinations that are possible from… (More)
There is reason to believe in the existence of a minimal length that can in principle be measured. This viewpoint stems in part from the realization that if enough massenergy is confined to a small… (More)
We show that solutions for the masses and mixings of the quarks and leptons based on a U (1)×Z 2 horizontal symmetry are possible. The seesaw mechanism is shown to work consistently in the presence… (More)
We show that the equivalence theorem approximating one-loop gauge sector diagrams by including only Goldstone bosons in the loop gives a remarkably poor approximation to the amplitude for the decay H… (More)
We show how introducing discrete Abelian flavor symmetries can produce texture zeros in the fermion mass matrices, while preserving the correct relationships with the low-energy data on quark and… (More)
Supersymmetric models with Lorentz violation can be formulated in super-space. Two theories based on the Wess-Zumino model are discussed. A com-pactification of superspace can be employed to… (More)

A new variational characterization of solutions for an important class of nonlinear operator equations is obtained. The result obtained is used to derive sharp necessary and sufficient conditions for… (More)
Supersymmetry and Lorentz invariance are closely related as both are spacetime symmetries. Terms can be added to Lagrangians that explicitly break either supersymmetry or Lorentz invariance. It is… (More)
