Considerations concerning the fluctuations of the ratios of two observables

Abstract : We discuss several possible caveats which arise with the interpretation of measurements of fluctuations in heavy-ion collisions. We especially focus on the ratios of particle yields, which have been advocated as a possible signature of a critical point in the QCD phase diagram. We conclude that current experimental observables are not well defined and are without a proper quantitative meaning.
