Spin Structure of the Nucleon: Overview
Yoshitaka Hatta
I present a pedagogical review of the decomposition of the proton spin. Both the Jaffe-Manohar and Ji decompositions are discussed. Particular emphasis is placed on the quark and g…
Mass radius and D-term of atomic nuclei in relativistic mean field theory
Yoshitaka Hatta, Tomohiro Oishi, Makoto Oka
Based on relativistic mean field theory for atomic nuclei, we compute the mass radius and other radii associated with the energy momentum tensor for dozens of spin-0 nuclei across…
Quantum entanglement in electron-nucleus collisions: Role of the linearly polarized gluon distribution
Michael Fucilla, Yoshitaka Hatta, Bo-Wen Xiao
We calculate the spin density matrix of a back-to-back quark-antiquark pair inclusively produced in electron-nucleus scattering, taking into account the gluon saturation effect and…
Single spin asymmetry in
Yoshitaka Hatta, Oleg V. Teryaev
We study an exotic type of single spin asymmetry in unpolarized electron-proton scattering, in which the outgoing electron momentum exhibits a left-right asymmetry relative to the…
Realizing the Scientific Program with Polarized Ion Beams at EIC
Grigor Atoian, Nigel Buttimore, Giuseppe Ciullo +67
Polarized ion beams at the Electron Ion Collider are essential to address some of the most important open questions at the twenty-first century frontiers of understanding of the fu…
Directed flow from parton spin-orbit coupling in and collisions
Sanjin BeniÄ, Yoshitaka Hatta
We point out a novel mechanism to generate two-particle azimuthal correlation (`directed flow') in unpolarized proton-proton and proton-nucleus collisions in the forward…
