Quantum tomography at the Electron-Ion Collider

Michael Fucilla, Yuxun Guo, Yoshitaka Hatta

We initiate the study of quantum state tomography---the experimental reconstruction of the complete spin density matrix---of massless and massive quark-antiquark pairs produced at…

Spin-spin entanglement at high energy

Michael Fucilla, Yoshitaka Hatta, Bo-Wen Xiao

Spin correlations offer a quantum-information perspective on the partonic final states produced in high-energy scattering. We discuss the spin-density matrix of a heavy quark-antiq…

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…

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…

Directed flow from parton spin-orbit coupling in and collisions

Sanjin Benić, 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 r…

Sullivan process near threshold and the pion gravitational form factors

Yoshitaka Hatta, Jakob Schoenleber

We propose a novel method to experimentally access the gravitational form factors (GFFs) of the charged pion through the Sullivan process in electron-proton scattering. We de…

Angular dependence in transverse momentum dependent diffractive parton distributions at small-

Yoshitaka Hatta, Feng Yuan

We discuss the angular dependence of the recently proposed transverse momentum dependent quark and gluon diffractive parton distributions at small-. We introduce the difractive…

Accessing the gravitational form factors of the nucleon and nuclei through a massive graviton

Yoshitaka Hatta

In contrast to the electromagnetic form factors of the nucleon and nuclei that have been extensively studied in electron scattering, there is no known way to directly measure the g…
