Abstract

In this letter, we implement a test of the standard law for the dark matter density evolution. For this purpose, only a flat universe and the validity of the FRW metric are assumed. A deformed dark matter density evolution law is considered, given by , and constraints on are obtained by using galaxy cluster gas mass fractions, and cosmic chronometers measurements. We find that within 2 c.l., in full agreement with other recent analyses.
