Ejectile Polarization for $^2 H(e,e'\vec p)n$ at GeV energies

TL;DR

This paper presents a relativistic calculation of the deuteron electrodisintegration process at GeV energies, analyzing ejectile polarization and the impact of spin-dependent final state interactions.

Contribution

It introduces a formalism for ejectile polarization with arbitrary spin projections and applies it to a relativistic model of the reaction including spin-dependent FSIs.

Findings

Calculated six relevant asymmetries in the reaction.

Demonstrated the significance of spin-dependent FSI contributions.

Provided insights into ejectile polarization effects at GeV energies.

Abstract

We perform a fully relativistic calculation of the $^2 H(e,e'\vec p)n$ reaction in the impulse approximation employing the Gross equation to describe the deuteron ground state, and we use the SAID parametrization of the full NN scattering amplitude to describe the final state interactions (FSIs). The formalism for treating the ejectile polarization with a spin projection on an arbitrary axes is discussed. We show results for the six relevant asymmetries and discuss the role of spin-dependent FSI contributions.
