Photon-nucleon entanglement in Compton scattering at low and high energies
Yoshitaka Hatta, Víctor Martínez-Fernández
We study spin-spin entanglement in the final state photon-nucleon system in Compton scattering, both at low energy below the pion threshold and at high energy in perturbative QCD t…
Probing quantum entanglement with Generalized Parton Distributions at the Electron-Ion Collider
Yoshitaka Hatta, Jakob Schoenleber
Within the collinear factorization framework based on Generalized Parton Distributions (GPDs), we calculate the spin density matrix of exclusively produced quark and antiquark pair…
Spin-spin entanglement in diffractive heavy quark production
Michael Fucilla, Yoshitaka Hatta
We calculate the spin density matrix of a heavy quark-antiquark pair (, or ) diffractively produced in Deep Inelastic Scattering and Ultraperipheral…
Deeply virtual -meson production near threshold
Yoshitaka Hatta, Henry T. Klest, Kornelija Passek-K. +1
We discuss exclusive -meson electroproduction off the proton near threshold within the GPD factorization framework. We propose the `threshold approximation' in which only the l…
Generalized parton distributions and gravitational form factors at large momentum transfer
Yoshitaka Hatta, Jakob Schoenleber
Within the soft collinear effective theory (SCET), we derive a factorization theorem which resums Sudakov logarithms to all orders in the quark-in-quark general…
