We report the measurement of charged hadron production at different pseudo-rapidity values in deuteron+gold as well as proton-proton collisions at √ sNN = 200GeV at RHIC. The nuclear modification factors RdAu and Rcp are used to investigate new behaviors in the deuteron+gold system as function of rapidity and the centrality of the collisions respectively.

To explain the production of light nuclei in heavy-ion collisions at extreme energies, we focus on deuteron case. A Gibbs ensemble chemical freeze-out is a prerequisite to investigate non-equilibrium evolution expanding fireball. Quantum statistical approaches allow describe correlations including bound state formation strongly interacting and hot system. We consider virial approach evaluate pr...

We calculate the forward unpolarised doubly-virtual Compton scattering (VVCS) off deuteron in framework of pionless effective field theory, up to next-to-next-to-next-to-leading order (N3LO) for longitudinal and next-to-leading (NLO) transverse amplitude. The charge elastic form factor deuteron, obtained from residue VVCS amplitude, is used extract value single unknown two-nucleon one-photon co...

The birefringence effect in the nuclear pseudoelectric field of matter and an external electric field for a particle (deuteron, nucleus) moving in a storage ring is discussed. The influence of the birefringence effect on the EDM measurement experiments is considered. The attention is drawn to the possibility to measure the spin-dependent amplitude of the elastic coherent scattering of a deutero...

The deuteron deep inelastic unpolarized structure function F 2 is calculated using the Wilson operator product expansion method. The long distance behaviour, related to the deuteron bound state properties, is evaluated using the Bethe–Salpeter equation with one particle on–mass–shell. The calculation of the ratio F 2 D/2F 2 N is compared with other convolution models showing important deviation...

The study presented in this paper shows that accounting for the relativistic structure of the deuteron allows to explain the ratio of the Drell-Yan pair production cross-section at the low Bjorken x off the deuteron and the proton. Thus, the sea quark distributions in the nucleon should be studied with accounting for the effects of the relativistic structure of the deuteron. The suggested appro...

Recent interest in short range correlations of bound nucleons gave rise to our interest in the light front treatement of quasi-elastic electron deuteron scattering. The end goal of this research project is to examine the difference in cross sections between tensor polarized and unpolarized deuteron. This paper explores the simple case of scalar electron-deuteron scattering to determine whether ...

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...

We propose a measurement of double-polarization observables in the d(~e, e′~ p) reaction to investigate the spin structure of the deuteron. The individual components P ′ x and P ′ z, measured in parallel kinematics and in a broad range of pm, will reveal the dynamics of the deuteron spin structure and the manifestation of the D-state component in the deuteron ground-state wave-function. This wi...

Chiral-odd gluon transversity distribution could shed light on a new aspect of hadron physics. Although we had much progress recently quark distributions, there is no experimental measurement the transversity. The trasversity does not exist in spin-1/2 nucleons and it exists spin-1 deuteron. Therefore, probe physics deuteron beyond basic bound system proton neutron because cannot contribute dir...
