Nuclear inclusive scattering with polarized protons

Small Angle Scattering of Polarized Protons

Experiment E950 at AGS, BNL has provided data with high statistics for the left-right asymmetry of proton-carbon elastic scattering in the Coulomb-nuclear interference region of momentum transfer. It allows to access information about spin properties of the Pomeron and has practical implications for polarimetry at high energies. Relying on Regge factorization the results for the parameter r5, r...

Inclusive Scattering of 500-MeV Protons and Pionic Enhancement of the Nuclear Sea-Quark Distribution

%e have measured a complete set of polarization-transfer observables in the inclusive scattering of 500-MeV protons from 'H and Pb at q =1.75 fm '., Axial longitudinal and transverse response functions derived from these data show no differences between Pb and H. This implies no enhancement of the nuclear pion field in heavy nuclei and consequently that models of the low-x 3 dependence of certa...

Inclusive quasielastic scattering of polarized electrons from polarized nuclei

The inclusive quasielastic response functions that appear in the scattering of polarized electrons from polarized nuclei are computed and analyzed for several closed-shell-minus-one nuclei with special attention paid to K. Results are presented using two models for the ejected nucleon | when described by a distorted wave in the continuum shell model or by a plane wave in PWIA with onand o -shel...

Parity violating asymmetries in the scattering of transversely polarized protons.

Polarized Protons in HERA

Polarized proton beams at HERA can currently only be produced by extracting a beam from a polarized source and then accelerating it in the three synchrotrons at DESY. In this paper, the processes which can depolarize a proton beam in circular accelerators are explained, devices which could avoid this depolarization in the DESY accelerator chain are described, and specific problems which become ...
