Measures of charge fluctuations in nuclear collisions

  • The properties of two measures of charge fluctuations D-tilde and DeltaPhiq are discussed within several toy models of nuclear collisions. In particular their dependence on mean particle multiplicity, multiplicity fluctuations, and net electric charge are studied. It is shown that the measure DeltaPhiq is less sensitive to these trivial biasing effects than the originally proposed measure D-tilde. Furthermore the influence of resonance decay kinematics is analyzed and it is shown that it is likely to shadow a possible reduction of fluctuations due to QGP creation.
