Radiation dominated era and the power of general relativity [PDF]
Christian CordaAn analysis in the framework of the radiation dominated era permits to put bounds on the weak modification of general relativity which arises from the Lagrangian R^{1+epsilon}. Such a theory has been recently discussed in various papers in the literature. The new bounds together with previous ones in the literature rule out this theory in an ultimate way.View original: http://arxiv.org/abs/1205.6954
