B Hadron properties measured in the D0 experiment
The study of charm and beauty mesons and baryons provides many opportunities to not only measure and classify their spectroscopic states, but also it serves as a testing ground for aspects of flavor QCD such as heavy quark effective theory and lattice gauge calculations, that are used in precise calculations of masses, lifetimes and cross sections. The Fermilab Tevatron has provided both fixed target and proton--antiproton collider facilities that not only account for the discovery of b-quarks but also have dovetailed well with the b-factories to answer a variety of b-physics questions, some of which were not readily explored at existing e{sup +} e{sup -} and electron-positron colliders. An added feature of the hadron colliders is their large cross-section and high luminosity for production of b-quark states that compliments the high luminosities of the b-factories. We report on the observation of b-hadron states reconstructed using the D0 detector data at the Tevatron Collider. Measurements of the mass and relative rates of neutral excited B{sub d} and B{sub s} mesons, and the discovery of the {Xi}{sub b} baryon are described

PROJECTED LAB-E DICROMATIC ELECTRONIC DETECTOR FACILITY
Two years ago the first neutrino interaction had yet to be observed at Fermilab. It was not known at that time whether the cross section would continue to rise above 10 GeV (in fact there were indications from cosmic ray experiments to the contrary), or even whether a W-boson might exist with a mass of say 2.5 GeV/c{sup 2}. Put in this perspective the progress in neutrino physics has been truly outstanding. Let us just review briefly the primary results so far reported by the Caltech-Fermilab group. The physics can be divided into two parts: (A) the study of the structure of hadrons (deep inelastic scattering) and (B) the study of the weak interaction at high energies
Linear Collider Physics Resource Book for Snowmass 2001, 2: Higgs and Supersymmetry Studies
This Resource Book reviews the physics opportunities of a next-generation e+e- linear collider and discusses options for the experimental program. Part 2 reviews the possible experiments on Higgs bosons and supersymmetric particles that can be done at a linear collider.This Resource Book reviews the physics opportunities of a next-generation e+e- linear collider and discusses options for the experimental program.
