Three-qubit entanglement in the Bethe-Heitler process
Haotian Cao, Yuxun Guo, Yoshitaka Hatta +1
The familiar Bethe-Heitler process on the proton target is transformed into a laboratory for studying multiparticle entanglement. We discuss how bipartite and genuin…
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…
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 generali…
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…
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 le…
Twist analysis of the spin-orbit correlation in QCD
Yoshitaka Hatta, Jakob Schoenleber
We present a QCD analysis of the twist-three parton distribution functions associated with the spin-orbit correlation of quarks and gluons in spin- and spin-0 hadrons.…
