Instanton induced transverse single spin asymmetry for production in -scattering
N. Korchagin, N. Kochelev, Pengming Zhang
We calculate the production cross-section and the transverse single-spin asymmetry for pion in . Our computation is based on existence of the instanton i…
Corrections of two-photon interactions in the fine and hyperfine structure of the P-energy levels of muonic hydrogen
A. E. Dorokhov, N. I. Kochelev, A. P. Martynenko +2
In the framework of the quasipotential method in quantum electrodynamics we calculate corrections to the nuclear structure proportional to from two-photon exchange amplitud…
The contribution of pseudoscalar and axial-vector mesons to hyperfine structure of muonic hydrogen
A. E. Dorokhov, N. I. Kochelev, A. P. Martynenko +3
In the framework of the quasipotential method in quantum electrodynamics we calculate the contribution of light pseudoscalar (PS) and axial-vector (AV) mesons to the interaction op…
Gluonic Distribution in the Constituent Quark and Nucleon Induced by the Instantons
Baiyang Zhang, Nikolai Kochelev, Hee-Jung Lee +1
Instanton effects can give large contribution to strong interacting processes, especially at the energy scale where perturbative QCD is no longer valid. However instanton contribut…
Single-spin asymmetries in SIDIS induced by anomalous gluon-quark and photon-quark couplings
Xu Cao, Nikolai Korchagin, Nikolai Kochelev +1
We calculate the contribution of the non-perturbative Pauli couplings in the quark-photon and quark-gluon vertices to the single-spin asymmetries (SSAs) in semi-inclusive deep inel…
Exotic glueball states in QCD Sum Rules
Alexandr Pimikov, Hee-Jung Lee, Nikolai Kochelev +2
The lowest dimension three-gluon currents that couple to the exotic glueballs have been constructed using the helicity formalism. Based on the constructed currents, we o…
