Ghost anomalous dimension in asymptotically safe quantum gravity
We compute the ghost anomalous dimension within the asymptotic-safety scenario for quantum gravity. For a class of covariant gauge fixings and using a functional renormalization group scheme, the anomalous dimension ηc is negative, implying an improved UV behavior of ghost fluctuations. At the non-G...
