Soft Pion Emission from the Nucleon Induced by Twist-2 Light-Cone Operators
N. Kivel, M. V. Polyakov, S. Stratmann
We compute the matrix elements for pion emission from the nucleon induced by twist-two light-cone operators in the kinematics where the pion is close to threshold. It is shown that…
Comment on the Theta+ width and mass
Dmitri Diakonov, Victor Petrov, Maxim Polyakov
We discuss the relatively low mass and narrow width prediction for the exotic baryon Theta+, and comment on recent statements by R.L. Jaffe on the subject. We reaffirm that a narro…
Spontaneously Broken Chiral Symmetry and Hard QCD Phenomena
M. J. Amarian, V. M. Braun, S. J. Brodsky +28
These are the mini-proceedings of the workshop ``Spontaneously Broken Chiral Symmetry and Hard QCD Phenomena" held at the Physikzentrum Bad Honnef from July 15 to 19, 2002. Every a…
On "dual" parametrizations of generalized parton distributions
M. V. Polyakov, A. G. Shuvaev
We propose a parametrization for the generalized parton distributions (GPDs) which is based on representation of parton distributions as an infinite series of t-channel exchanges.…
Quark distribution functions in the chiral quark-soliton model: cancellation of quantum anomalies
K. Goeke, P. V. Pobylitsa, M. V. Polyakov +2
In the framework of the chiral quark-soliton model of the nucleon we investigate the properties of the polarized quark distribution. In particular we analyse the so called anomalou…
Nucleon matrix elements of twist-3 and 4 operators from the instanton vacuum
J. Balla, M. V. Polyakov, C. Weiss
The spin-dependent twist-3 and 4 nucleon matrix elements d^(2) and f^(2) describing power corrections to the Bjorken and Ellis-Jaffe sum rules are computed in the instanton vacuum.…
