We study the role played by the Landau–Pomeranchuk–Migdal (LPM) effect in relativistic collisions of hadrons and heavy nuclei, within a parton cascade model. We find that the LPM effect strongly affects the gluon multiplication due to radiation and considerably alters the spacetime evolution of the dynamics of the collision. It ensures a multiplicity distribution of hadrons in agreement with the experimental...
We study the elliptic flow v 2 of multi-strange hadrons such as the φ, Ξ and Ω as a function of transverse momentum in the recombination and fragmentation model and compare to a standard hydrodynamic calculation. We find that the measurement of v 2 for the φ and Ω will allow for the unambiguous distinction between parton recombination and statistical hadro-chemistry to be the dominant...
