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${\bf 103}$,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.
