Deuteron Break-up: Theoretical Description of Polarization Observables in Stapp Formalism

نویسنده

  • O. G. Grebenyuk
چکیده

The vector Ay and tensor Ayy analyzing powers as well as the polarization of the outgoing proton are calculated for the exclusive deuteron break-up reaction ~ dp → ~ ppn at a deuteron beam energy of 2 GeV. Two component covariant formalism of Stapp has been used to have the completely Lorentz invariant model. In addition to the Impulse Approximation the nucleon-nucleon double-scattering and deltaexcitation mechanism have been added coherently. Good agreement with the precise data obtained at Saclay is achieved . PACS: 21.45+v, 24.70+s, 25.10+s

NONDYNAMICAL ANALYSIS OF SPIN AMPLITUDES IN PION-PROTON ELASTIC SCATTERING IN OPTIMAL FORMALISM AT 6.0 GeV/C

Optimal conditions are used in nondynamical formalism to diagonalize the pionproton reaction matrix as much as possible. Invariance laws are imposed to simplify the relationship between observables and bilinear combination of amplitudes. Transverse amplitudes are determined by using measured polarization parameter in xfp elastic scattering at 6.0 GeVIC

اندازه‌گیری مشاهده‌پذیرهای کانال تجزیه سه‌جسمی برای بخشی از فضای فاز پراکندگی دوترون- دوترون در انرژی برنوکلئون

Information obtained from nucleus as a bound system of nucleons and from nucleon-nucleon scattering experiments is a strong tool for studying various aspects of nuclear forces. Deuteron-deuteron scattering as a four-nucleon system can provide useful information. So, scattering experiment of a polarized beam of deuteron with kinetic energy of65 MeV/nucleon from a liquid-deuterium target was done...

Parity violation in quasifree electron scattering off the deuteron

For deuteron electroweak disintegration, parity violating effects are investigated which arise from the interference of γ and Z exchange as well as from the hadronic sector via a small parity violating component in the deuteron. The general formalism for the differential cross section and polarization observables of electromagnetic deuteron disintegration is extended to incorporate parity viola...

A Comment on General Formulae for Polarization Observables in Deuteron Electrodisintegration and Linear Relations

We establish a simple, explicit relation between the formalisms employed in the treatments of polarization observables in deuteron two-body electrodisintegration published by Arenhövel, Leidemann, and Tomusiak in Few-Body Systems 15, 109 (1993) and the results of the present authors published in Phys. Rev. C 40, 2479 (1989). We comment on the overlap between the two sets of results. In a recent...
