Describing hadronic structure is one of the most intriguing problems in physics. GPDs provide exhaustive information on this respect. Starting from pion LFWFs and relying on the covariant extension formalism, we design a novel path towards GPD models fulfilling every theoretical constraint required by QCD. We exploit them to obtain predictions for DVCS on pions at EIC kinematics, showing gluon dom ... More

Proton, the most common hadron in the universe, have a puzzle in their charge radius. Accurate knowledge of the radius is very important to understand how quantum chromodynamics (QCD) works in the non-perturbative region. ULQ2 experiment aims to obtain the most reliable radius for electron scattering. Commissioning of the new beamline and spectrometers is ongoing, and physics run will start from F ... More

GPDs provide a 3D picture of the nucleon, and the hard exclusive pion production have been providing important inputs for understanding the chiral-odd GPDs. The Jefferson Lab Hall A experiment E12-06-014 extended the kinematic coverage in the quark valence regime, and has measured the cross section of exclusive $\pi^0$ production off protons at large values of $x_B$ (0.36, 0.48, and 0.60) and $Q^2 ... More Presented by Po-Ju LIN on 28/7/2021 at 10:00 Type: Parallel Session: QCD and hadron structure-A4 Track: QCD and Hadron Structure The wide-angle photo- and electroproduction of pions is investigated within the handbag mechanism in which the$\gamma^{(*)} N\to \pi N'$amplitudes factorize into subprocess amplitudes,$\gamma^{(*)} q\to \pi q'$, and form factors representing$1/x$-moments of generalized parton distributions (GPDs). The subprocess is calculated to twist-3 accuracy taking into account both the 2- and 3-body Fock ... More Presented by Kornelija PASSEK-KUMERICKI on 28/7/2021 at 9:20 Type: Leading parallel Session: QCD and hadron structure-A4 Track: QCD and Hadron Structure In this talk, we show how the 3-dimensional partonic structure of nuclear targets can be accessed in deeply virtual Compton scattering processes. The proper planning of these experiments at Jefferson Lab and at the future Electron-Ion Collider requires Monte Carlo (MC) event generators able to account for the exact treatment of nuclear effects. After a description of such models for the$^4\$He nuc ... More
