Phys. Rev. Lett. 92, 181102 (2004) [4 pages]Skewness as a Test of the Equivalence PrincipleReceived 17 December 2003; published 6 May 2004 The skewness of the large-scale distribution of matter has long been known to be a probe of gravitational clustering. Here we show that the skewness is also a probe of violation of the equivalence principle between dark matter and baryons. The predicted level of violation can be tested with the forthcoming data from the Sloan Digital Sky Survey. © 2004 The American Physical Society URL:
