Multiplicity distributions in gravitational and strong interactions
arXiv:1005.5343 · doi:10.1016/j.physletb.2010.07.004
Abstract
The multiplicity distributions produced by the variation of time-dependent gravitational fields in a conformally flat background geometry belong to the same class of infinitely divisible distributions found, for fixed centre of mass energies and symmetric (pseudo)rapidity intervals, in charged multiplicities produced in , and in heavy ion collisions. Apparently unrelated multiplicity distributions are classified in terms of the (positive) discrete representations of the group. The gravitational analogy suggest a global high-energy asymptote for the distributions measured in and collisions. Second-order cross correlations between positively and negatively charged distributions represent a relevant diagnostic for a closer scrutiny of the multiparticle final state.
