Kinematical Ambiguities in Scattering by Deuteron
نویسنده
چکیده
We discuss the kinematical ambiguities occurring in the definition of the twobody amplitudes in particle-deuteron scattering. We show how the ,value of the energy parameter is uniquely determined through the proper reduction from the three-body to the two-body matrix elements. This ,value is compared to previously used prescriptions, and shown to give superior fitting when compared with experimental data on elastic pion deuteron scattering at low and medium energies. * Work supported in p&r% by the Energy Research and Development Administration. jPermanent addresses.

Radiative corrections to deep – inelastic ed − scattering
The model–independent radiative corrections to deep–inelastic scattering of unpolarized electron beam off the tensor polarized deuteron target have been considered. The contribution to the radiative corrections due to the hard–photon emission from the elastic electron–deuteron scattering (the so–called elastic radiative tail) is also investigated. The calculation is based on the covariant param...
متن کاملInvestigation of the Neutron Structure Function via Semi-inclusive Deep Inelastic Electron Scattering off the Deuteron
The production of slow nucleons in semi-inclusive deep inelastic electron scattering off the deuteron is investigated in the region x ∼ > 0.3 for kinematical conditions accessible at HERA. Within the spectator mechanism the semi-inclusive cross section exhibits a scaling property, which can be used as a model-independent test of the dominance of the spectator mechanism itself, providing in this...

We study deeply virtual Compton scattering (DVCS) on a deuteron target. We model the Generalized Quark Distributions in the deuteron by using the impulse approximation for the lowest Fock-space state. Numerical predictions are given for the unpolarized cross sections for the kinematical regimes relevant for JLab and HERMES at HERA. Differential cross sections show the same pattern as for the pr...
متن کاملProbing short-range nucleon correlations in high-energy hard quasielastic pd reactions.
We show that the strong dependence of the amplitude for NN hard scattering on the collision energy can be used to magnify the effects of short range nucleon correlations in quasielastic pd scattering. Under specific kinematical conditions the effect of initial and final state interactions can be accounted for by rescaling the cross section calculated within the plane wave impulse approximation....
متن کاملDeep Electroproduction of Photons and Mesons on the Deuteron
We study deeply virtual Compton scattering and deep exclusive meson electroproduction on a deuteron target. We model the Generalized Quark Distributions in the deuteron by using the impulse approximation for the lowest Fock-space state on the light-cone. We study the properties of the resulting GPDs, and verify that sum rules violations are quite small in the impulse approximation. Numerical pr...
