On gravitational dressing of renormalization group β-functions beyond lowest order of perturbation theory
نویسنده
چکیده
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.

On scheme dependence of gravitational dressing of renormalization group functions
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.
متن کاملNon-Perturbative Tachyon Potential from the Wilsonian Renormalization Group
The derivative expansion of the Wilsonian renormalization group generates additional terms in the effective β-functions not present in the perturbative approach. Applied to the nonlinear σ model, to lowest order the vanishing of the β-function for the tachyon field generates an equation analogous to that found in open string field theory. Although the nonlinear term depends on the cut-off funct...
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.
