Studying time-like proton form factors using vortex state annihilation
Nikolai Korchagin
Vortex states of particles - non-plane-wave solutions of the corresponding wave equation with a helicoidal wave front - open new opportunities for particle physics, unavailable in…
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…
Twisted particle collisions: a new tool for spin physics
Igor P. Ivanov, Nikolai Korchagin, Alexandr Pimikov +1
Collisions of twisted particles --- that is, non-plane-wave states of photons, electrons, or any other particle, equipped with a non-zero orbital angular momentum (OAM) with respec…
Kinematic surprises in twisted particle collisions
Igor P. Ivanov, Nikolai Korchagin, Alexandr Pimikov +1
"Twisted particles" refer to non-plane-wave states of photons, electrons, hadrons, or any other particle which carry non-zero, adjustable orbital angular momentum with respect to t…
Doing spin physics with unpolarized particles
Igor P. Ivanov, Nikolai Korchagin, Alexandr Pimikov +1
Twisted, or vortex, particles refer to freely propagating non-plane-wave states with helicoidal wave fronts. In this state, the particle possesses a non-zero orbital angular moment…
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…
Anomalous Quark Chromomagnetic Moment and Dynamics of Elastic Scattering
Nikolai Kochelev, Nikolai Korchagin
We estimate the contribution of nonperturbative quark-gluon chromomagnetic interaction to the high energy elastic proton-proton cross section at large momentum transfer. It is show…
Anomalous Quark Chromomagnetic Moment and Single-Spin Asymmetries
Nikolai Kochelev, Nikolai Korchagin
We discuss a nonperturbative mechanism for the single-spin asymmetries (SSA) in the strong interaction. This mechanism is based on the existence of a large anomalous quark chromoma…
Anomalous quark-gluon chromomagnetic interaction and high energy -meson electroproduction
Nikolai Korchagin, Nikolai Kochelev, Nikolai Nikolaev
It is shown that existence of a large anomalous chromomagnetic moment of quark induced by non-perturbative structure of QCD leads to the additional contribution to exclusive -me…
