Rapidity Distributions of Hadrons in Proton-Nucleus Collisions
H. J. Pirner, B. Kopeliovich
We study proton-lead collisions with a new model for the Fock states of the incoming proton. The number of collisions which the proton experiences selects the appropriate Fock stat…
J/Psi in high-multiplicity pp collisions: lessons from pA
B. Z. Kopeliovich, H. J. Pirner, I. K. Potashnikova +2
Gluons at small x in high-energy nuclei overlap in the longitudinal direction, so the nucleus acts as a single source of gluons, like higher Fock components in a single nucleon, wh…
Heavy quarkonium production: Nontrivial transition from pA to AA collisions
B. Z. Kopeliovich, I. K. Potashnikova, H. J. Pirner +1
Two novel QCD effects, double color filtering and mutual boosting of the saturation scales in colliding nuclei, affect the transparency of the nuclei for quark dipoles in compariso…
Quantum-mechanical description of in-medium fragmentation
B. Z. Kopeliovich, H. -J. Pirner, I. K. Potashnikova +3
We present a quantum-mechanical description of quark-hadron fragmentation in a nuclear environment. It employs the path-integral formulation of quantum mechanics, which takes care…
Diffractive photo- and leptoproduction of vector mesons , and
G. Kulzinger, H. G. Dosch, H. J. Pirner
We calculate diffractive photo- and leptoproduction of -, - and -mesons. The incoming photon dissociates into a -dipole which scatters on the nucleon and tran…
QCD Phase Transition in Hot Hadronic Matter
H. J. Pirner, B. -J. Schaefer
We analyse the QCD chiral phase transition in the nonlinear and linear -model. The strategy is the same in both cases. We fix the parameters of the effective meson theory at tem…
