Multiplicity Distributions and Charged-neutral Fluctuations
Results from the multiplicity distributions of inclusive photons and charged particles, scaling of particle multiplicities, event-by-event multiplicity fluctuations, and chargedneutral fluctuations in 158·A GeV Pb+Pb collisions are presented and discussed. A scaling of charged particle multiplicity as N part and photons as N 1.12±0.03 part have been observed, indicating violation of naive wound...
متن کاملPolarization Correlations in Pair Production from Charged and Neutral Strings
Polarization correlations of ee pair productions from charged and neutral Nambu strings are investigated, via photon and graviton emissions, respectively and explicit expressions for their corresponding probabilities are derived and found to be speed dependent. The strings are taken to be circularly oscillating closed strings, as perhaps the simplest solution of the Nambu action. In the extreme...
متن کاملCentrality Dependence of the Charged-Particle Multiplicity Density at Midrapidity
Quantum chromodynamics (QCD), the theory of the strong interaction, predicts a phase transition at high temperature between hadronic and deconfined matter (the quark-gluon plasma). Strongly interacting matter under such extreme conditions can be studied experimentally using ultrarelativistic collisions of heavy nuclei. The field entered a new era in November 2010 when the Large Hadron Collider ...
متن کاملCharged Particle Angular Correlations from Leading Photons at RHIC
The behavior at high-pT in heavy ion collisions at RHIC is currently not well understood. Two interesting observations have been made so far. First, there is a significant suppression in the yield of high-pT particles relative to the expected yield from binary scaling [1]. Second, high-pT particles have a strong v2 correlation to the reaction plane which is constant with pT [2]. There have been...
متن کاملMoments of the Charged-particle Multiplicity Distribution in Z Decays at Lep
The charged-particle multiplicity distribution and its moments have been measured, for all hadronic as well as for light-quark and b-quark events in ee collisions at the Z mass. The Hq moments derived from the charged-particle multiplicity distribution are known to exhibit quasi-oscillations when plotted versus the order of the moment. This behavior is predicted by the NNLLA of perturbative QCD...
