Fixed Points of Nonlinear Sigma Models in d>2
A. Codello, R. Percacci
Using Wilsonian methods, we study the renormalization group flow of the Nonlinear Sigma Model in any dimension , restricting our attention to terms with two derivatives. At one…

Ultraviolet properties of f(R)-Gravity
Alessandro Codello, Roberto Percacci, Christoph Rahmede
We discuss the existence and properties of a nontrivial fixed point in f(R)-gravity, where f is a polynomial of order up to six. Within this seven-parameter class of theories, the…

Fixed Points of Higher Derivative Gravity
A. Codello, R. Percacci
We recalculate the beta functions of higher derivative gravity in four dimensions using the one--loop approximation to an Exact Renormalization Group Equation. We reproduce the bet…
