Abstract: I will discuss the studies of supersymmetry which can be done at a 500 GeV e+e- linear collider. These include precision measurements of masses of (lighter) superpartners and also their couplings.

Abstract: A proposal for a comprehensive e+e- physics program was done at SLAC. The project plans to use an asymmetrical collider consisting of the PEP-II LER and a new electron storage ring (VLER) of energy between 140 MeV and 500 MeV, to be constructed in the IR-12 hall at PEP-II. The accessible center of mass energies will then be between 1.4 GeV and 2.5 GeV. This is an energy regime that is inadequately explored in electron-positron annihilations. While there are many important physics measurements that are feasible at this collider, emphasis will be put on R, the ratio of the hadron and muon pair cross sections, and on the determination of nucleon, hyperon and meson timelike form factors.

Abstract: I will present results of a study by J. Brau, C. Potter, and M. Iwasaki first presented at LCWS 2000. Updated results from optimizing a neural network analysis will also be presented. The results will be compared to three previous Higgs branching ratio studies. Finally, I will briefly discuss the study's implications for the Minimal Supersymmetric Model Higgs sector.

Abstract: Gamma-ray bursts (GRBs) are the most electromagnetically luminous objects observed in the universe, yet their origin remains elusive. Observing GRBs in the TeV energy range can be extremely valuable in providing insight into GRB radiation mechanisms and in constraining source distances. The Milagrito detector was an air shower array which used the water Cherenkov technique to search for TeV sources. Data from this detector was analyzed to look for a TeV component of GRBs coincident with low energy gamma-rays detected by the BATSE instrument on the Compton Gamma Ray Observatory. The results of this analysis, including evidence for a candidate TeV GRB, will be presented.

Abstract: A precise measurement of the anomalous magnetic moment of the positive
muon has been made by Experiment E821 at the Brookhaven Alternating
Gradient Synchrotron. Analysis of 950 million 
+ decays to e+,
taken in the 1999 run, yields a statistical uncertainty of 1.3 ppm, which is
a third of that of combined previous data. The result
am+ = 11 659 202(14)(6) x 10^-10 is in good agreement
with previous measurement. The theoretical value from the standard
model is am+(SM) = 11 659 160(7) x 10-10 and
am+(exp) - am+(SM) = 42(16) x 10-10 where
am+(exp) is the world average experimental value.
