Polarized Protons for ISABELLEn AGS, produces polarized beams. For polarized protons in ISABELLE, the injection energy has to be lowered to about 22 GeV, and one or two “Siberian Snakes” have to be installed to eliminate resonances. Magnet imperfections may still have some depolarizing effect, especially at high energies; howeve

Acceleration of Polarized Proton at the AGS led us to attempt to accelerate polarized protons in the AGS. A collaborative effort is underway by the groups in Argonne, Michigan, Rice, Yale and Brookhaven to improve and modify the AGS to accelerate polarized protons. With the appropriate funding the first polarized proton acceleration at the A

Recent Results of Polarization in Inclusive Hyperon Production at Fermilabstudies continue and new results will be reported. The A polarization from hydrogen has been studied in detail to determine dependence on kinematic variables. Polarization from heavy targets has been measured for inclusively produced Ξ°, Ξ., and Σ. hyperons. A simple model of quark-antiquark pair pr

Spin and Flavour at Short Distanceseem to play a crucial role in our understanding of hadrons and their physical properties. Quarks carry spin and appear to participate even in the most inelastic interactions in an extrenely simple and well defined fashion. A review of their role in several important reactions is presented.

Spin Effects in Perturbative Quantum Chromodynamicsn particular, exclusive processes including hadronic decays of heavy quark resonances have the potential of isolating QCD hard scattering subprocesses in situations where the helicities of all the interacting constituents are controlled. The predictions can be summarized in terms of QCD spin selecti
