Real Compton Scattering via Color Dipoles
B. Z. Kopeliovich, Ivan Schmidt, M. Siddikov
We study photoabsorption reaction and real Compton scattering (RCS) within the color dipole model. We rely on a photon wave function derived in the instanton vacuum model, and on t…
DVCS via color dipoles: Nonperturbative effects
B. Z. Kopeliovich, Ivan Schmidt, M. Siddikov
We study the DVCS amplitude within the color dipole approach. The light-cone wave function of a real photon is evaluated in the instanton vacuum model. Our parameter free calculati…
Azimuthal Asymmetry of pions in pp and pA collisions
B. Z. Kopeliovich, A. H. Rezaeian, Ivan Schmidt
We investigate the azimuthal asymmetry v2 of produced pions in pp and pA collisions at both RHIC and SPS energies. In our approach, based on the pQCD parton model and the light-con…
Azimuthal anisotropy of direct photons
B. Z. Kopeliovich, H. J. Pirner, A. H. Rezaeian +1
The electromagnetic bremsstrahlung produced by a quark interacting with nucleons or nuclei is azimuthally asymmetric. In the light-cone dipole approach this effect is related to th…
Jet lag effect and leading hadron production
B. Z. Kopeliovich, H. -J. Pirner, I. K. Potashnikova +1
We propose a solution for the long standing puzzle of a too steeply falling fragmentation function for a quark fragmenting into a pion, calculated by Berger [1] in the Born approxi…
Charmed Meson Production in Deep Inelastic Scattering
B. Floter, B. Z. Kopeliovich, H. J. Pirner +1
Charmed meson production in semi-inclusive deep inelastic scattering is investigated in the color dipole formalism. The transverse momentum distributions are calculated. We find go…
