The dysprosium parity violation experiment concluded nearly 17 years ago with an upper limit on weak interaction induced mixing of nearly degenerate, opposite parity states in atomic dysprosium. While that experiment was limited in…
Recent and preliminary single-particle data are presented from the AGS Experiment 866 at BNL. Emphasis is put on the transverse mass as well as the rapidity distributions of charged pions, kaons, protons, deuterons and anti-protons measured…
The field of Generalized Parton Distribution (GPD) benefited from a wealth of exclusive reactions measurements since 2000. Extraction of GPDs from observables has begun with this first generation of experiments. In the short and mid-term…
Data from KEK on subthreshold antiproton as well as on pi(+-) and K(+-) production in proton-nucleus reactions are described at projectile energies between 3.5 and 12.0 GeV. We use a model which considers a hadron-nucleus reaction as an…
The emission of particles after atomic muon capture was studied extensively during the early 70's. In particular, proton and neutron spectra were measured in order to determine whether nuclear emission was due to a direct or a thermalized…
The Muon g-2 collaboration has measured the anomalous magnetic g value, a = (g-2)/2, of the positive muon with an unprecedented uncertainty of 0.7 parts per million. The result, based on data collected in the year 2000 at Brookhaven…
The parton momentum densities in the proton are obtained from a NLO QCD analysis of structure functions measured by HERA and fixed target experiments. The uncertainties in these parton densities, the structure functions and related cross…
We use detailed balance for a hadron composed of quark and gluon Fock states to obtain parton distributions in the proton and pion on the basis of a simple statistical model.
Polarized proton collisions will be studied at RHIC up to a total center of mass energy of 500 GeV, starting in 2002. An overview of the RHIC-spin program, and the critical components of the PHENIX and STAR detectors for spin experiments,…
