SU(3) systematization of baryons
V. Guzey, M. V. Polyakov
We review the spectrum of all baryons with the mass less than approximately 2000-2200 MeV using methods based on the approximate flavor SU(3) symmetry of the strong interaction. Th…
SU(3) prediction of a new Lambda baryon
V. Guzey
Using the approximate flavor SU(3) symmetry of strong interactions, we argue for the existence of a new Lambda baryon with J^P=3/2^-, the mass around 1850 MeV, the total width of a…
Self-compression and catastrophic collapse of photon bullets in vacuum
M. Marklund, B. Eliasson, P. K. Shukla
Photon-photon scattering, due to photons interacting with virtual electron-positron pairs, is an intriguing deviation from classical electromagnetism predicted by quantum electrody…
Sivers effect in semi-inclusive deeply inelastic scattering and Drell-Yan
J. C. Collins, A. V. Efremov, K. Goeke +5
The Sivers function is extracted from HERMES data on single spin asymmetries in semi-inclusive deeply inelastic scattering. The result is used for making predictions for the Sivers…
Comparing extractions of Sivers functions
M. Anselmino, M. Boglione, J. C. Collins +11
A comparison is given of the various recently published extractions of the Sivers functions from the HERMES and COMPASS data on single-transverse spin asymmetries in semi-inclusive…
Sivers effect in Drell Yan at RHIC
J. C. Collins, A. V. Efremov, K. Goeke +5
On the basis of a fit to the Sivers effect in deep-inelastic scattering, we make predictions for single-spin asymmetries in the Drell-Yan process at RHIC.
Evolution Equation for Generalized Parton Distributions
M. Kirch, A. Manashov, A. Schafer
The extension of the method [arXiv:hep-ph/0503109] for solving the leading order evolution equation for Generalized Parton Distributions (GPDs) is presented. We obtain the solution…
Axial-vector form factors of the nucleon within the chiral quark-soliton model and their strange components
Antonio Silva, Hyun-CHul Kim, Diana Urbano +1
We investigate three different axial-vector form factors of the nucleon, , , , within the framework of the SU(3) chiral quark-soliton model, emphasizing thei…
On the A-dependence of nuclear generalized parton distributions
V. Guzey, M. Siddikov
We perform a microscopic evaluation of nuclear GPDs for spin-0 nuclei in the framework of the Walecka model. We demonstrate that the meson (non-nucleon) degrees of freedom dramatic…
Sivers effect in semi-inclusive deeply inelastic scattering
J. C. Collins, A. V. Efremov, K. Goeke +3
The Sivers function is extracted from HERMES data on single spin asymmetries in semi-inclusive deeply inelastic scattering. Our analysis use a simple Gaussian model for the distrib…
Dual parameterization of generalized parton distributions and description of DVCS data
V. Guzey, M. V. Polyakov
We discuss a new leading-order parameterization of generalized parton distributions of the proton, which is based on the idea of duality. In its minimal version, the parameterizati…
Meson-loop contributions to the quark condensate from the instanton vacuum
Hyun-Chul Kim, M. M. Musakhanov, M. Siddikov
We investigate the quark condensate of the QCD vacuum within the instanton vacuum model. We calculate the meson-loop contributions to the dynamical quark mass and quark condensate…
Photoproduction of the Theta^+ resonance on the nucleon in a Regge model
H. Kwee, M. Guidal, M. V. Polyakov +1
We estimate the reaction mechanisms for the photoproduction of the Theta^+(1540) resonance on the nucleon, through K and K^* Regge exchanges. We compare the size of the cross secti…
Leading twist nuclear shadowing and suppression of hard coherent diffraction in proton-nucleus scattering
V. Guzey, M. Strikman
We use the Glauber-Gribov multiple scattering formalism and the theory of leading twist nuclear shadowing to develop a method for the calculation of leading twist hard coherent dif…
Inequalities for nucleon generalized parton distributions with helicity flip
M. Kirch, P. V. Pobylitsa, K. Goeke
Several positivity bounds are derived for generalized parton distributions (GPDs) with helicity flip.
QCD Analytic Perturbation Theory. From integer powers to any power of the running coupling
A. P. Bakulev, S. V. Mikhailov, N. G. Stefanis
We propose a new generalized version of the QCD Analytic Perturbation Theory of Shirkov and Solovtsov for the computation of higher-order corrections in inclusive and exclusive pro…
Extraction of radiative decay width for the non-strange partner of Theta^+
Ya. Azimov, V. Kuznetsov, M. V. Polyakov +1
Using the results of the GRAAL collaboration on the ηphotoproduction from the neutron target, we attempt to extract the partial radiative width of the possible new nucleon resonanc…
Proton-nucleus scattering and cross section fluctuations at RHIC and LHC
V. Guzey, M. Strikman
We consider high-energy proton-heavy nucleus scattering within the framework of the Glauber-Gribov approximation and taking into account cross section fluctuations. Fixing paramete…
Parameterization of the quark-quark correlator of a spin-1/2 hadron
K. Goeke, A. Metz, M. Schlegel
The general parameterization of the quark-quark correlation function for a spin-1/2 hadron is considered. The presence of the Wilson line ensuring color gauge invariance of the cor…
