Net-charge fluctuations in relativistic heavy-ion interactions

Nystrand, Joakim LU ; Stenlund, Evert LU and Tydesjö, Henrik LU (2003) In Physical Review C: covering nuclear physics 68.
Abstract
Different measures of net-charge fluctuations in ultrarelativistic heavy-ion interactions, namely, v(Q), v(R), Γ and νdyn, are discussed and compared. Their behaviors are confronted in the context of different experimental scenarios. It is found that the νdyn observable exhibits most of the experimentally desirable features. The v(Q) and Γ observables are also appropriate although proper care must be taken of finite acceptance and efficiency effects. Two simple charged particle production models are considered; production via neutral resonance decay and hadronization from a quark-gluon plasma. The study reveals that dynamical correlations, arising in such models, strongly influence the measures.
