Event-by-event fluctuations of transverse momentum and multiparticle clusters in relativistic heavy-ion collisions

Abstract

We analyze the event-by-event fluctuations of mean transverse momentum measured recently by the PHENIX and STAR Collaborations at RHIC. We argue that the observed scaling of strength of dynamical fluctuations with the inverse number of particles can be naturally explained by formation of multiparticle clusters.

Summary talk for ISMD 06

“…Cramer argued that there may be coherent scattering combined with absorption at late time in the collision, and that this can modify the conclusions [40]. Perhaps some of ideas described by Florkowski concerning multiple correlations and jest may be useful in sorting all of this out [41].…”

Multiparticle Production at High Multiplicities

“…In project Thermalization we plan to verify these. There are many of experimental and theoretical results, which evidence of cluster nature of MP by significant short-range multiplicity correlations [15], the observed scaling of the dynamical fluctuations of mean transverse-momentum [16].…”
