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 fromâ€¦ (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 smallâ€¦ (More)

We show that solutions for the masses and mixings of the quarks and leptons based on a U (1)Ã—Z 2 horizontal symmetry are possible. The seesaw mechanism is shown to work consistently in the presenceâ€¦ (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 Hâ€¦ (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 andâ€¦ (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 toâ€¦ (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 forâ€¦ (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 isâ€¦ (More)
