      A likelihood analysis of the observables in deeply virtual exclusive processes is presented to derive a joint likelihood of the structure function parametrizing the deeply virtual Compton scattering cross section in QCD, for each observed combination of the kinematic variables defining the reaction.
      The analysis includes twist-three corrections to the cross section formalism. In our...

      Obtaining the $x$-dependent GPDs is crucial for understanding hadron tomography, but it has been hindered by low sensitivity in most known experimental processes like the DVCS and TCS. In this talk, I will compare those processes with new ones that offer enhanced sensitivity to the $x$-dependence. By using a pixelated GPD construction, we can visualize point-by-point sensitivity. I will also...

    4. 25. Finite-element evolution code for generalized parton distributions

      Talk

      Generalized parton distributions (GPDs) are functions of four variables, one of which is a renormalization scale. The functional dependence on this renormalization scale is fully determined by a renormalization group equation---or "evolution equation"---that can be derived from perturbative QCD. A fast numerical implementation of the scale evolution is vital to any global phenomenology effort,...

    5. 11. Trace anomaly form factors from lattice QCD

      Talk

      The hadron mass can be obtained through the calculation of the trace of the energy-momentum tensor in the hadron which includes the trace anomaly and sigma terms. The trace anomaly form factor can provide information about the mass distribution within hadrons and can be accessed through the gravitational form factors (GFFs) which are the moments of GPD. In this talk, I will present the...
