Spatial imaging of polarized deuterons at the Electron-Ion Collider
Abstract
We study diffractive vector meson production at small-𝑥 in the collision of electrons and polarized deuterons 𝑒 + 𝑑↑. We consider the polarization dependence of the nuclear wave function of the deuteron, which results in an azimuthal angular dependence of the produced vector meson when the deuteron is transversely polarized. The Fourier coefficients extracted from the azimuthal angular dependence of the vector meson differential cross-section exhibit notable differences between longitudinally and transversely polarized deuterons. The angular dependence of the extracted effective deuteron radius provides direct insight into the structure of the polarized deuteron wave function. Furthermore, we observe slightly increased gluon saturation effects when the deuteron is longitudinally polarized compared to the transversely polarized case. The small-𝑥 observables studied in this work will be accessible at
the future Electron-Ion Collider.
