Skewness as a test of the equivalence principle

Abstract

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 forecoming data from the Sloan Digital Sky Survey.
