On the twist-3 contribution to h_L in the instanton vacuum
B. Dressler, M. V. Polyakov
We show that the instanton model of the QCD vacuum indicates the parametric smallness of the twist-3 contributions to the polarized structure function h_L. This smallness is relate…
Hard exclusive electroproduction of decuplet baryons in the large N_c limit
L. L. Frankfurt, M. V. Polyakov, M. Strikman +1
The cross sections and transverse spin asymmetries in the hard exclusive electroproduction of decuplet baryons are calculated in the large N_c limit and found to be comparable to t…
Hard diffractive electroproduction of two pions
B. Lehmann-Dronke, P. V. Pobylitsa, M. V. Polyakov +2
We have calculated the leading order amplitude of hard diffractive electroproduction of two pions in lepton nucleon scattering. At the leading twist level a pion pair can be produc…
Helicity skewed quark distributions of the nucleon and chiral symmetry
M. Penttinen, M. V. Polyakov, K. Goeke
We compute the helicity skewed quark distributions and in the chiral quark-soliton model of the nucleon. This model emphasizes correctly the role of…
On the search for a narrow penta-quark Z baryon in NN interactions
M. V. Polyakov, A. Sibirtsev, K. Tsushima +2
The possibility for an observation of a narrow penta-quark baryon in reactions is discussed. It is shown that the reaction at excess energies around 100…
Skewed and double distributions in pion and nucleon
M. V. Polyakov, C. Weiss
We study the non-forward matrix elements of twist-2 QCD light-ray operators and their representations in terms of skewed and double distributions, considering the pion as well as t…
