The forward-backward multiplicity correlation coefficient is calculated for arbitrary nucleus-nucleus collision in the framework of the wounded nucleon model. Discussion of our results in the context of the preliminary AuAu collisions STAR data is presented. PACS: 25.75.-q, 25.75.Gz

We review results on hadron multiplicities in high energy particle collisions. Both theory and experiment are discussed. The general procedures used to describe particle multiplicity in Quantum Chromo-dynamics (QCD) are summarized. The QCD equations for the generating functions of the multiplicity distributions are presented both for fixed and running coupling strengths. The mean multiplicities...

The study of partition statistics can be said to have begun with Erdős and Lehner [3] in 1941, who studied questions concerning the normal, resp. average value over all partitions of n of quantities such as the number of parts, the number of different part sizes, and the size of the largest part. To begin with, instead of looking at parts in partitions we will look at gaps, that is, at part siz...

Event classifiers based either on the charged-particle multiplicity or event shape have been extensively used in proton-proton (pp) collisions by ALICE collaboration at LHC. The use of these tools became very instrumental since observation fluid-like behavior high-multiplicity pp collisions. In particular, study as a function registered forward V0 detector allowed for discovery strangeness enha...

In this paper‎, ‎we prove a multiplicity result for some biharmonic elliptic equation of Kirchhoff type and involving nonlinearities with critical exponential growth at infinity‎. ‎Using some variational arguments and exploiting the symmetries of the problem‎, ‎we establish a multiplicity result giving two nontrivial solutions‎.

This study draws on extensive ethnographic data and a multiple case design to develop new theory about innovation processes techniques. By contrasting the experiences outcomes of five projects in an educational technology company, considers two distinct, if often interrelated, strategies navigating market uncertainty: building testing. The paper theorizes how appropriate balance between these i...

the subject of the present article is the problem concerning the unity of attributes and its relation to the unity of referent and multiplicity of concepts. in this problem, the theory of non-revealingness (‘adam-i kāshifiyat) of the multiplicity of concepts from multiplicity of referent is proved; and the rival theory, i.e., the revealingness of the multiplicity of concept from the multiplicit...
