To see the exotic Theta^+ baryon from interference
Moskov Amarian, Dmitri Diakonov, Maxim V. Polyakov
Since all couplings of the exotic baryon to normal hadrons seem to be small it is hard to reveal it in standard resonance searching. We suggest to look for the producti…
Collins Effect in SIDIS and in Annihilation
A. V. Efremov, K. Goeke, P. Schweitzer
We review the present understanding of the nucleon transversity distribution and Collins fragmentation function, based on Ref.\cite{Efremov:2006qm}, and discuss how Drell-Yan exper…
Transverse single spin asymmetries in inclusive deep-inelastic scattering
A. Metz, M. Schlegel, K. Goeke
In inclusive deep-inelastic lepton-hadron scattering multi-photon exchange between the leptonic and the hadronic part of the process causes single spin asymmetries. The asymmetries…
Semi-inclusive deep inelastic scattering at small transverse momentum
Alessandro Bacchetta, Markus Diehl, Klaus Goeke +3
We study the cross section for one-particle inclusive deep inelastic scattering off the nucleon for low transverse momentum of the detected hadron. We decompose the cross section i…
K*-couplings for the antidecuplet excitation
Ya. Azimov, V. Kuznetsov, M. V. Polyakov +1
We estimate the coupling of the K* vector meson to the N-->Theta+ transition employing unitary symmetry, vector meson dominance, and results from the GRAAL Collaboration for eta ph…
Strange nucleon form factors: Solitonic approach to , , and and comparison with world data
Klaus Goeke, Hyun-Chul Kim, Antonio Silva +1
We summarize the results of the chiral quark-soliton model (QSM) concerning basically all form factors necessary to interpret the present data of the parity violating electron s…
Photon acceleration in vacuum
J. T. Mendonca, M. Marklund, P. K. Shukla +1
A new process associated with the nonlinear optical properties of the electromagnetic vacuum, as predicted by quantum electrodynamics, is described. This can be called photon accel…
Radiative corrections to hard spectator scattering in decays
Nikolai Kivel
We present the calculation of the next-to-leading corrections to the tree amplitudes which appear in the description of non-leptonic B-decays in the factorization approach. These c…
The dual parameterization of the proton generalized parton distribution functions H and E and description of the DVCS cross sections and asymmetries
V. Guzey, T. Teckentrup
We develop the minimal model of a new leading order parameterization of GPDs introduced by Shuvaev and Polyakov. The model for GPDs H and E is formulated in terms of the forward qu…
Fractional Analytic Perturbation Theory in Minkowski space and application to Higgs boson decay into a b\bar{b} pair
A. P. Bakulev, S. V. Mikhailov, N. G. Stefanis
We work out and discuss the Minkowski version of Fractional Analytic Perturbation Theory (FAPT) for QCD observables, recently developed and presented by us for the Euclidean region…
Instanton contribution to the Sivers function
I. O. Cherednikov, U. D'Alesio, N. I. Kochelev +1
We study the Sivers function for valence u and d quarks in the proton within the instanton model for QCD vacuum, adopting the MIT bag model wave functions for quarks. Within approa…
Light-cone divergence in twist-3 correlation functions
L. P. Gamberg, D. S. Hwang, A. Metz +1
It is argued that the definition of the twist-3 transverse momentum dependent correlation functions must be modified if they contain light-like Wilson lines. In the framework of a…
Electric properties of the baryon anti-decuplet in the SU(3) chiral quark-soliton model
Tim Ledwig, Hyun-Chul Kim, Antonio Silva +1
We investigate the electric form factors and charge radii of the pentaquark baryons within the framework of the chiral quark-soliton model. We consider the rotational and l…
Improvement of the Theta+ width estimation method on the Light Cone
Cédric Lorcé
Recently, Diakonov and Petrov have suggested a formalism in the Relativistic Mean Field Approximation allowing one to derive the 3-, 5-, 7-,... quark wavefunctions for the octet, d…
Collins effect in semi-inclusive deeply inelastic scattering and in electron positron annihilation
A. V. Efremov, K. Goeke, P. Schweitzer
The Collins fragmentation function is extracted from HERMES data on azimuthal single spin asymmetries in semi-inclusive deeply inelastic scattering, and BELLE data on azimuthal asy…
Parity-violating aysmmetries in elastic scattering in the chiral quark-soliton model: Comparison with A4, G0, HAPPEX and SAMPLE
Antonio Silva, Hyun-Chul Kim, Diana Urbano +1
We investigate parity-violating electroweak asymmetries in the elastic scattering of polarized electrons off protons within the framework of the chiral quark-soliton model (QSM)…
Nuclear shadowing in inclusive and tagged deuteron structure functions and extraction of F_2^p-F_2^n at small x from electron-deuteron collider data
L. Frankurt, V. Guzey, M. Strikman
We review predictions of the theory of leading twist nuclear shadowing for inclusive unpolarized and polarized deuteron structure functions F_2^D, g_1^D and b_1^D and for the tagge…
Checking the Burkardt sum rule for the Sivers function by model calculations
K. Goeke, S. Meissner, A. Metz +1
The Sivers mechanism gives rise to a non-zero average transverse momentum of partons inside a transversely polarized target. According to a sum rule of Burkardt this transverse mom…
