Gravitational dressing of the renormalization group
Abstract
We study the gravitational dressing of renormalizable two-dimensional field theories. Our main result is that the one-loop β function is finitely renormalized by the factor (k+2)/(k+1), where k is the central charge of the gravitational SL(2,R) current algebra.
