The structure of the virtual photon and its contribution to small x processes in deep inelastic scattering at HERA is discussed.

In this article, we take the point of view that the X(1835) be a baryonium state and calculate its mass within the framework of the QCD sum rules approach. The numerical values of the X(1835) are consistent with the experimental data. There must be some baryonium component in the X(1835) state. PACS number: 12.38.Aw, 12.38.Qk

In the context of the Feynman’s derivation of electrodynamics, we show that noncommutativity allows other particle dynamics than the standard formalism of electrodynamics.

We compute amplitude of deeply virtual Compton scattering in the parton model. We found that the amplitude in the hard regime up to the accuracy O(1/Q) depends on new skewed parton distributions (SPD's). These additional contributions make the DVCS amplitude explicitly transverse. The new SPD's contribute to various spin, charge and azimuthal asymmetries at the same order in 1/Q as the leading ...
