ar X iv : h ep - p h / 06 01 10 5 v 4 2 D ec 2 00 6 X ( 1835 ) as a baryonium state with QCD sum rules

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 value of the mass of the X(1835) is consistent with the experimental data. There may be some baryonium component in the X(1835) state. PACS number: 12.38.Aw, 12.38.Qk

Using a combination of S-Matrix and perturbative QCD properties in the small x Bj regime, we propose a formulation of hard diffraction unifying the partonic (Ingelman-Schlein) Pomeron, Soft Colour Interaction and QCD dipole descriptions.

B-meson light-cone distribution amplitudes are discussed in these lectures in the framework of HQET. The evolution equation for the leading-twist distribution amplitude is derived in one-loop approximation. QCD sum rules for distribution amplitudes are discussed.
