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...
The theoretical analysis of the $^{2}\mathrm{H}{(d,p)}^{3}\mathrm{H}$ reaction taking place in both metallic as well gaseous targets at deuteron energies several keV presented here indicates a strong contribution single-particle ${0}^{+}$ threshold resonance. Additional arguments based on weak coupling between 2 + and 3 1 clustering states compound nucleus $^{4}\mathrm{He}$ support this resonan...
Anomalous enhancement of DD-reaction, alpha emission and X-ray generation in the high current pulsing deuterium glow-discharge with Ti-cathode at the voltages ranging from 0.8-2.5 kV. ABSTRACT Using electronic noiseless solid state plastic track (CR-39) and Al 2 O 3 :C thermo-luminescent (TLD) detectors, the yields of charged particles (DD-reaction products and long-r a n g e α-particles) and X...
We present a system-level description of the Low Frequency Instrument (LFI) considered as a differencing polarimeter, and evaluate its expected performance. The LFI is one of the two instruments on board the ESA Planck mission to study the cosmic microwave background. It consists of a set of 22 radiometers sensitive to linear polarisation, arranged in orthogonally-oriented pairs connected to 11...
The S–wave scattering length of the strong pion–deuteron (πD) scattering is calculated in the relativistic field theory model of the deuteron suggested in [1,2].The theoretical result agrees well with the experimental data. The important role of the ∆–resonance contribution to the elastic πD–scattering is confirmed. PACS: 11.10. Ef, 12.39. Fe, 13.75. Cs, 13.75 Gx
