On scheme dependence of gravitational dressing of renormalization group functions
نویسنده
چکیده
It is shown that for 2D field theories only the first order coefficient of the gravitationally dressed RG β-function is scheme independent. This is valid even for matter theories with one dimensionless coupling, where the first two coefficients of the original β-function are scheme independent.

On gravitational dressing of renormalization group β-functions beyond lowest order of perturbation theory
Based on considerations in conformal gauge I derive up to nextleading order a relation between the coefficients of β-functions in 2D renormalizable field theories before and after coupling to quantized gravity. The result implies a coupling constant dependence of the ratio of both β-functions beyond leading order.
متن کاملPhysical Scaling and Renormalization Group in Two-Dimensional Gravity
Quantum gravitational effects on the renormalization group equation are studied in the (2+ ǫ)-dimensional approach. Divergences in a matter one-loop effective action do not receive gravitational radiative corrections. The renormalization factor for beta functions recently found by Klebanov, Kogan and Polyakov is obtained by using the renormalized cosmological constant to define the physical sca...
متن کاملGravitational Dressing of Renormalization Group
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.
متن کاملImpact of topology in foliated quantum Einstein gravity
We use a functional renormalization group equation tailored to the Arnowitt-Deser-Misner formulation of gravity to study the scale dependence of Newton's coupling and the cosmological constant on a background spacetime with topology [Formula: see text]. The resulting beta functions possess a non-trivial renormalization group fixed point, which may provide the high-energy completion of the theor...
متن کاملTowards c = 0 flows
We discuss some implications of the gravitational dressing of the renormalization group for conformal field theories perturbed by relevant operators. The renormalization group flows are defined with respect to the dilatation operator associated with the J (0) 0 mode of the SL(2, R) affine algebra. We discuss the possibility of passing under the c = 25 barrier along renormalization group flows i...
