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 del...

The (2)H(e,e'p)n cross section at a momentum transfer of 3.5 (GeV/c)(2) was measured over a kinematical range that made it possible to study this reaction for a set of fixed missing momenta as a function of the neutron recoil angle θ(nq) and to extract missing momentum distributions for fixed values of θ(nq) up to 0.55  GeV/c. In the region of 35°≤θ(nq)≤45° recent calculations, which predict th...

Photodisintegration of the deuteron above-threshold is studied in a coupled channel approach including N-and d-channels with pion retardation in potentials and exchange currents.

Motivated by recent advances in the application of effective field theory techniques to light nuclei we revisit the problem of electron-deuteron scattering in these approaches. By sidestepping problems with the description of electron-nucleon scattering data in effective field theories, we show that the effective theory expansion for deuteron physics converges well over a wide range of momentum...

Pionless effective field theory with dibaryon fields is reexamined for observables involving the deuteron. The electromagnetic form factors of the deuteron and the total cross section of radiative neutron capture on the proton, n p → d γ, are calculated. The low energy constants of vector(photon)-dibaryon-dibaryon vertices in the effective lagrangian are fixed primarily by the one-body vector(p...

We consider deuteron formation in hot and dense nuclear matter close to equilibrium and evaluate the life-time of the deuteron fluctuations within the linear response theory. To this end we derive a generalized linear Boltzmann equation where the collision integral is related to equilibrium correlation functions. In this framework we then utilize finite temperature Green functions to evaluate t...

L. Frankfurt, M. Sargsian, M. Strikman (a) Tel Aviv University, Tel Aviv, Israel (b) Pennsylvania State University, University Park, PA, USA (d) S.Petersburg Nuclear Physics Institute, Russia (e) Yerevan Physics Institute, Yerevan, Armenia Abstract: The exclusive and inclusive electroproduction off the polarized deuteron is considered at large Q and x ≥ 0.5. It is shown that the use of a polari...

The proton, neutron and deuteron structure functions F2(x,Q 2) and g1(x,Q 2), measured at intermediate Q2, are analyzed within a Regge approach. This analysis serves to fix the parameters of this scheme which are then used to calculate, in a unified Regge approach, the properties of ρ0 meson electroproduction on the proton and the deuteron. In this way, the double-spin asymmetry observed at HER...

The spin-dependent structure function of the deuteron, g 1D , is calculated within a covariant framework. The off-shell structure of the bound nucleon gives corrections to the convolution model at a level of half a percent for x below 0.7, increasing to more than five percent at larger x. Overall, the dominant source of error comes from the lack of knowledge associated with the deuteron D-state...

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 experim...
