Probing the nuclear gluon distribution with heavy quarks
J. Raufeisen
The color dipole formulation provides an intuitive picture of hard processes in high energy scattering. Most importantly, this approach allows one to calculate nuclear effects in a…
Dilepton Transverse Momentum in the Color Dipole Approach
M. A. Betemps, M. B. Gay Ducati, M. V. T. Machado +1
We investigate the Drell-Yan transverse momentum distribution in the framework of the color dipole approach. Special attention is paid to parton saturation effects at high energies…
QCD coherence effects in low-x DIS and Drell-Yan with nuclear targets
J. Raufeisen
We investigate QCD coherence effects in deep inelastic scattering (DIS) off nuclei and in Drell-Yan (DY) dilepton production in proton-nucleus collisions within the light-cone colo…
The color dipole approach to the Drell-Yan process in pA collisions
B. Z. Kopeliovich, J. Raufeisen, A. V. Tarasov
In the target rest frame and at high energies, Drell-Yan (DY) dilepton production looks like bremsstrahlung of massive photons, rather than parton annihilation. The projectile quar…
QCD coherence effects in high energy reactions with nuclei
J. Raufeisen
In this work, coherence effects in deep inelastic scattering (DIS) and in the Drell-Yan (DY) process off nuclei are investigated, in particular nuclear shadowing. The target rest f…
Nuclear Shadowing in DIS at Moderately Small
J. Raufeisen, A. V. Tarasov, O. O. Voskresenskaya
In the rest frame of the nucleus, shadowing is due to hadronic fluctuations of the incoming virtual photon, which interact with the nucleons. We expand these fluctuations in a basi…
