  1. 79. Extraction of TMDs from experimental data
    Alessandro Bacchetta (PV)
    24/09/2015, 09:00
    Invited talk
    I will review the current status of the extraction of Transverse Momentum Distributions (TMDs) from experimental data. We are gaining an ever increasing knowledge about TMDs, both unpolarized and polarized, but we are still far from a precise determination of these quantities. Central issues are currently related to the implementation of TMD evolution in the extractions. To make further...

  2. 23. Deeply virtual Compton scattering: sensitivities to the three Compton form factors
    Bernard Bakker (VU University)
    24/09/2015, 09:30
    Invited talk
    In scalar QED the number of Compton form factors is known to be five. The case where the incoming photon is virtual, namely produced by electron scattering, while the final photon is real, the physical amplitudes depend on only three of them. We study the sensitivity of the differential cross section to the subleading Compton form factors.

  3. 15. Hermes results on 3D imaging of the nucleon
    Mr Luciano Libero Pappalardo (FE)
    24/09/2015, 10:00
    Invited talk
    In the context of rapid theoretical developments in non-perturbative QCD, a formalism of Transverse Momentum Dependent parton distribution functions (TMDs) and of Generalized Parton Distributions (GPDs) was introduced in the last two decades, providing a more comprehensive multi-dimensional description of the nucleon. TMDs and GPDs allow in fact for complementary descriptions of the nucleon in...

  4. 60. Flavor Asymmetry of the Proton Sea in Chiral Effective Theory
    Prof. Chueng-Ryong Ji (NCSU)
    24/09/2015, 10:30
    Invited talk
    While the leading nonanalytic behavior in chiral effective theory must be universal, there has been a puzzling factor 4/3 difference in the coefficient of the leading nonanalytic contribution to the vertex renormalization constant of the nucleon or equivalently that of the pion for more than a decade. We have recently resolved this lingering factor difference by carefully analyzing the vertex...
