One Loop Chiral Corrections to Hard Exclusive Processes:I. Pion Case

N. Kivel, M. V. Polyakov

We computed the leading non-analytic chiral corrections to the generalized parton distributions (GPDs) of the pion and to the two-pion distribution amplitudes. This allows us to ob…

A note on inequalities for the masses of the lightest pi-pi resonances in large N_c QCD

M. V. Polyakov, V. V. Vereshagin

We derive and analyse inequalities relating masses of the lightest pi-pi resonances (rho and sigma) to low energy couplings of the effective chiral Lagrangian in the limit of large…

DVCS on the nucleon to the twist-3 accuracy

N. Kivel, M. V. Polyakov

The amplitude of the deeply virtual Compton scattering off nucleon is computed to the twist-3 accuracy in the Wandzura-Wilczek (WW) approximation. The result is presented in the fo…

Wandzura-Wilczek approximation for the twist-3 DVCS amplitude

N. Kivel, M. V. Polyakov, A. Schafer +1

We present a derivation of Wandzura-Wilczek (WW) like relations for skewed parton distributions. It is demonstrated for photon-pion scattering that the skewed twist-3 parton distri…

Hard exclusive production of two pions: Dipion mass distributions in gamma* N -->pi pi N and gamma* gamma --> pi pi

M. V. Polyakov

The leading twist parametrization of dipion mass distribution in hard exclusive reactions is proposed. Its parameters are related to quark distributions (usual and skewed) in the p…

Effective Chiral Lagrangian from Dual Resonance Models

M. V. Polyakov, V. V. Vereshagin

Parameters of the effective chiral lagrangian (EChL) of orders and are extracted from low--energy behaviour of dual resonance models for and scattering…
