Relativistic description of polarized-deuteron fragmentation accompanied by the emission of high-transverse-momentum protons

Tensor A yy and vector A y analyzing powers in the 1H(d, d′)X and 12C(d, d′)X reactions at initial deuteron momenta of 9 GeV/c in the region of baryonic resonance excitation

“…The results on the tensor A yy and vector A y obtained at 9 GeV/c and 85 mrad [4] and at 5 GeV/c and 178 mrad [5] have been satisfactorily explained in the framework of the PWIA approach [12] (see diagram in Fig. 5a).…”

“…The observed independence of the analyzing powers on the atomic number of the target indicates that rescattering in the target and medium effects are small. Hence, nuclear targets are also appropriate to obtain information on the baryonic excitation in inelastic deuteron scattering [1]- [5].…”

“…It was pointed out that the spin-dependent part of the N N → N N * (∼ 2.2 GeV/c 2 ) amplitude is significant. Recent measurements of the tensor A yy and vector A y analyzing powers in the vicinity of the excitation of baryonic resonances with masses up to ∼ 1.8 GeV/c 2 [4,5] demonstrated large spin effects and the sensitivity to the baryonic resonances properties. The exclusive measurements in the H(d, d…”

“…Inelastic scattering of polarized deuterons on hydrogen and nuclei at high energies has been investigated during the last decade in Dubna [1]- [5] and Saclay [6,7]. The main goal of these studies is to investigate the properties of the baryonic resonances via measurements of polarization observables in the (d, d…”

Proposal of the experiment on the investigation of the (d, p) reaction at the extracted deuteron beam of the U-70 accelerator

“…Such a function was found by Carbonell and Karmanov within the framework of the light-front dynamics [12]. This function, in distinction to the non-relativistic wave functions, allowed the experimental data on the tensor analyzing power of the nuclear fragmentation of relativistic deuterons to be qualitatively described [13].…”
