Comment on $\frac{K}{\pi }$ Fluctuations at Relativistic Energies

Abstract

We discuss the $\frac{K}{\pi }$ fluctuations in relativistic heavy ion collisions reported by the STAR collaboration, PRL$103$,092301(2009), also discussed by the NA49 collaboration at SPS-CERN. We show that these fluctuations could be explained simply by imposing strangeness and charge conservations.
