We briefly discuss the problem of specifying initial conditions for evolution of off-diagonal (skewed) parton distributions. We present numerical results to show that evolution rapidly washes out differences of input. Off-diagonal (or skewed) parton distributions provide important information about the nonper-turbartive structure of the nucleon [ 1]. They can in principle be measured in such pr...

I discuss how generalized parton distribution probe various aspects of QCD bound states. Topics include the interplay between transverse and longitudinal structure, quantum mechanical interference, orbital angular momentum, helicity flip, and higher-spin targets. 1 Before talking about spin My assignment is to speak about spin aspects of generalized parton distributions. Before doing so I would...

A search for Θ + (1540) and Ξ −− 3/2 (1860) pentaquark candidates has been performed in proton-induced reactions on C, Ti and W targets at √ s = 41.6 GeV studying the pK 0 S resp. Ξ − π − and Ξ − π + (and charge conjugated (c.c.)) decay channels at mid-rapidity. With sensitivities of Br×dσ/dx F < 5 to 25 µb/nucleon, we find no evidence for narrow pentaquark peaks in any of the studied final sta...
