Net-charge fluctuations in relativistic heavy-ion interactions
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
