[en] The nucleon elastic form factors are generally interpreted as a mapping of the charge and magnetic current distributions of the proton and neutron. New high Q² measurements have opened up fundamental questions about G_ep that remain to be answered. This talk will summarize current developments surrounding the nucleon form factors and explain why they are important to neutrino physicists. New parameterizations of the nucleon form factors, suitable for use by neutrino physicists, will be introduced and discussed

[en] The energy resolution, linearity and e/π response of model SDC calorimeter configurations were measured. The configurations consisted of a fine sampling lead electromagnetic (EM) compartment and either a lead or iron hadronic (HAD) compartment. The data indicate that the lead-scintillator and iron-scintillator hadron calorimeters have comparable resolutions and linearity after a relative weighting of signals from the EM and HAD compartments is made

[en] We calculate the total and differential quasielastic cross sections for neutrino and antineutrino scattering on nucleons using up to date fits to the nucleon elastic electromagnetic form factors G_E^p, G_Eⁿ, G_M^p, G_Mⁿ, and GA and pseudoscalar form factors. We compare predictions of the cross sections for nucelons and nuclei to experimental data. (Presented by Arie Bodek at CIPANP2003, New York City, NY 2003)

[en] We present new parameterizations of vector and axial nucleon form factors. We maintain an excellent descriptions of the form factors at low momentum transfers, where the spatial structure of the nucleon is important, and use the Nachtman scaling variable ξ to relate elastic and inelastic form factors and impose quark-hadron duality constraints at high momentum transfers where the quark structure dominates. We use the new vector form factors to re-extract updated values of the axial form factor from neutrino experiments on deuterium. We obtain an updated world average value from ν_μd and pion electroproduction experiments of M_A=1.014±0.014 GeV/c². Our parameterizations are useful in modeling neutrino interactions at low energies (e.g. for neutrino oscillations experiments). The predictions for high momentum transfers can be tested in the next generation electron and neutrino scattering experiments. (orig.)

We use the new vector form factors to re-extract updated values of the axial form factor from ν_μ experiments on deuterium. We obtain an updated world average value from ν_μ d, v-bar _μH and pion electroproduction experiments of M_A 1.014 ± 0.014 GeV/c². Our parameterizations are useful in modeling v interactions at low energies (e.g. for v_μ oscillations experiments). The predictions for high Q² can be tested in the next generation electron and v_μ scattering experiments. (Presented by A.

[en] Three-jet events produced in e⁺e^- annihilations are used to provide comparisons between quark and gluon jets. Differences between quark-induced and gluon-induced jets are observed. Quark jets tend to have a more tightly collimated structure than gluon jets, which is reflected in the concentration of a larger fraction of the jet's energy near the jet axis

[en] This paper documents the fiber R and D for the CMS hadron barrel calorimeter (HCAL). The R and D includes measurements of fiber flexibility, splicing, mirror reflectivity, relative light yield, attenuation length, radiation effects, absolute light yield, and transverse tile uniformity. Schematics of the hardware for each measurement are shown. These studies are done for different diameters and kinds of multiclad fiber

[en] By studying e⁺e^- annihilations in the center-of-mass energy range between 50 and 60.8 GeV, we have established a 95%-confidence-level lower limit on the mass of a fourth-generation charge - 1/3 quark b' of 27.2 GeV. In contrast with all previous searches, this limit has been obtained through consideration of the decay processes b'→bγ and b'→bg aswell as b'→cW^-. For the cases where any one of the three decay modes dominates, we obtain higher mass limits

[en] A search for unstable heavy neutral leptons has been made at center-of-mass energies from 50 to 60.8 GeV with the AMY detector at the KEK Storage ring TRISTAN. The neutral leptons are assumed to decay via mixing to electrons and muons. Events with two leptons were searched for. No evidence for their existence was found. Limits in the mass range 7.8≤M_L⁰≤28.1 GeV/c² and mixing-parameter range 9x10^-10≤|U_lL|²≤1 are presented for Dirac- and Majorana-type neutrinos
