Spin observables of proton-deuteron elastic scattering at SPD NICA energies within the Glauber model and pN amplitudes

TL;DR

This paper uses the Glauber model with existing $pp$ and $pn$ amplitudes to predict spin observables in proton-deuteron elastic scattering at energies relevant for SPD NICA, providing a basis for experimental testing.

Contribution

It applies the spin-dependent Glauber theory with Regge parametrized $pN$ amplitudes to predict spin observables in $pd$ scattering at high energies, extending previous analyses.

Findings

Predicted spin observables can be measured at SPD NICA.

Provides a test for the $pN$ amplitudes used in the model.

Extends analysis to energies up to 50 GeV/c.

Abstract

A systematic analysis of nucleon-nucleon scattering amplitudes is available up to a laboratory energy of $3$~GeV in case of the $pp$ system and up to $1.2$ GeV for $pn$. At higher energies there is only incomplete experimental information on $pp$ elastic scattering, whereas data for the $pn$ system are very scarce. We apply the spin-dependent Glauber theory to calculate spin observables of $pd$ elastic scattering at $3$-$50$ GeV/c using $pp$ amplitudes available in the literature and parametrized within the Regge formalism. The calculated vector $A_y^p$, $A_y^d$ and tensor $A_{xx}$, $A_{yy}$ analyzing powers and the spin-correlation coefficients $C_{y,y}$, $C_{x,x}$, $C_{yy,y}$, $C_{xx,y}$ can be measured at SPD NICA and, thus, will provide a test of the used $pN$ amplitudes.
