We present a detailed analysis of the uncertainty in the neutron F(2n) structure function extracted from inclusive deuteron and proton deep-inelastic scattering data. The analysis includes experimental uncertainties as well as uncertainties associated with the deuteron wave function, nuclear smearing, and nucleon off-shell corrections. Correctly accounting for the Q(2) dependence of the data an...

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...

The contribution of nucleon isobar N exchanges to backward elastic pd-scattering is calculated on the basis of deuteron 6q-model and found to be negligible in comparison with the neutron exchange. It is shown that the pole amplitude of neutron pickup from the deuteron nN-component is favoured in the reaction pd → dN for backward going N(1440) and N(1710) at kinetic energy of incident proton of ...

We recently stored a 1.85 GeV/c vertically polarized deuteron beam in the COSY Ring in Jtilich; we then spin-flipped it by ramping a new air-core rf dipole's frequency through an rfinduced spin resonance to manipulate the polarization direction of the deuteron beam. We first experimentally determined the resonance's frequency and set the dipole's rf voltage to its maximum; then we varied its fr...

A COVARIANT DESCRIPTION OF THE DEUTERON AND A BUNCH OF OTHER STUFF A. Student Old Dominion University, 2014 Director: Dr. John Doe An introduction to the use of Bethe-Salpeter and quasipotential equations in the description of electron scattering from the deuteron is provided. The basic formalism and many technical issues are introduced in the context of a simple scalar theory. Results for boun...

We review predictions of the theory of leading twist nuclear shadowing for inclusive unpolarized and polarized deuteron structure functions F 2 , g 1 and b 1 and for the tagged deuteron structure function F 2 (x,Q, ~ p). We analyze the possibility to extract the neutron structure function F 2 from electron-deuteron data and demonstrate that an account of leading twist nuclear shadowing leads to...

The deuteron intra-bond dynamics of the deuteron glass phase in Rb0 68(N D 4)0 32D 2A s 0 4 has been studied by 2 D exchange NM R which extends the NM R observation window from the kHz region into the milli-Hertz region. The results show that the O D • • • O deuterons are indeed the basic reversible two-position dipoles in the structure and that deuteron intra-bond exchange and thus dipole reve...

We consider hadron production in deuteron gold collisions at RHIC in the forward rapidity region. Treating the target nucleus as a Color Glass Condensate and the projectile deuteron as a dilute system of valence quarks, we obtain good agreement with the BRAHMS minimum bias data on charged hadron production in the forward rapidity (y = 3.2) and low pt region. We provide predictions for neutral p...

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...
