Role of anomalous chromomagnetic interaction in Pomeron and Odderon structures and in gluon distribution
Nikolai Kochelev
We calculate the contribution arising from nonperturbative quark-gluon chromomagnetic interaction to the high energy total quark-quark cross section and to gluon distributions in n…
Single Spin Asymmetries in High Energy Reactions and Nonperturbative QCD Effects
A. E. Dorokhov, N. I. Kochelev, W. -D. Nowak
We discuss some experimental and theoretical results on single spin asymmetries (SSA) in high energy lepton-hadron and hadron-hadron reactions. In particular, recent results on mes…
Instanton interpolating current for --tetraquark
Hee-Jung Lee, N. I. Kochelev
We perform a QCD sum rule analysis for the light scalar meson () with a tetraquark current related to the instanton picture for QCD vacuum. We demonstrate that instan…
Soft Contribution to Quark-Quark Scattering Induced by an Anomalous Chromomagnetic Interaction
N. Kochelev
We calculate the soft contribution to high energy quark-quark scattering that arises from an instanton-induced quark anomalous chromomagnetic moment. We demonstrate that this is a…
Triquark correlations and pentaquarks in a QCD sum rule approach
Hee-Jung Lee, N. I. Kochelev, V. Vento
The role of quark correlations in the description of hadron dynamics in many domains of physics, from low energy dynamics to very hot(dense) systems, is being appreciated. Strong c…
A mechanism for the Double-Spin Asymmetry in Electromagnetic Production at HERMES
N. I. Kochelev, D. -P. Min, V. Vento +1
We calculate the contribution of meson and pomeron exchanges to the double-spin asymmetry in -meson electromagnetic production at HERMES energies. We show that the observed doub…
Anomalous Quark Chromomagnetic Moment Induced by Instantons
N. I. Kochelev
It is shown that the quark-gluon interaction induced by instantons leads to the quark anomalous chromomagnetic moment. In the instanton-liquid model for the QCD vacuum, the chromom…
