We analyse the proton and deutron data on spin dependent asymmetry A 1 (x, Q 2) supposing the DIS structure functions g 1 (x, Q 2) and F 3 (x, Q 2) have the similar Q 2-dependence. As a result, we have obtained Γ p

We show that the asymmetry in the fractional energy of charm versus an-ticharm jets produced in high energy diffractive photoproduction is sensitive to the interference of the Odderon (C = −) and Pomeron (C = +) exchange amplitudes in QCD. We predict the dynamical shape of the asymmetry in a simple model and estimate its magnitude to be of the order 15% using an Odd-eron coupling to the proton ...

We propose a unified and simple viewpoint to various evolution equations appropriate in different kinematic regions. We show that the resummation technique reduces to the Altarelli-Parisi equation, if the transverse degrees of freedom of a parton are ignored, to the Balitskii-Fadin-Kuraev-Lipatov equation, if the momentum fraction of a parton vanishes, and to the Gribov-Levin-Ryskin equation, i...

Some of the most difficult theoretical challenges of QCD occur at the interface of the perturbative and nonperturbative regimes. Exclusive and semi-exclusive processes, the diffractive dissociation of hadrons into jets, and hard diffractive processes such as vector meson leptoproduction provide new testing grounds for QCD and essential information on the structure of light-cone wavefunctions of...
