چکیده
Conformal scalar fields coupled to the dilaton appear naturally in two-dimensional models of black hole evaporation. We show that their trace anomaly is (1/24π)[R − 6(∇φ)2 − 22φ]. It follows that an RST-type counterterm appears naturally in the one-loop effective action. [email protected] [email protected]

متن کاملConformal Anomaly for Dilaton Coupled Theories from AdS/CFT Correspondence
Trace anomaly for dilaton coupled conformal theories on curved background with non-zero dilaton is found from supergravity side as an IR e ect using AdS/CFT correspondence. For d = 2 it coincides with the conformal anomaly for dilaton coupled scalar (up to total derivative term which is known to be ambiguous). In four-dimensional case we get conformal anomaly for N = 4 super YM theory interacti...
متن کاملEffective action and Hawking radiation for dilaton coupled scalars in two dimensions
The effective one-loop action for general dilaton theories with arbitrary dilaton-dependent measure and nonminimal coupling to scalar matter is computed. As an application we determine the Hawking flux to infinity from black holes in D-dimensions. We resolve the recently resurrected problem of an apparent negative flux for nonminimally coupled scalars: For any D ≥ 4 Black Hole the complete flux...
متن کاملScalar Potential and Dyonic Strings in 6 D Gauged Supergravity
In this paper we first give a simple parametrization of the scalar coset manifold of the only known anomaly free chiral gauged supergravity in six dimensions in the absence of linear multiplets, namely gauged minimal supergravity coupled to a tensor multiplet, E 6 × E 7 × U (1) R Yang-Mills multiplets and suitable number of hypermultiplets. We then construct the potential for the scalars and sh...
متن کاملBoundary Dynamics in Dilaton Gravity
We study the dynamics of the boundary in two dimensional dilaton gravity coupled to N massless scalars. We rederive the boundary conditions of [1] and [3] in a way which makes the requirement of reparametrization invariance and the role of conformal anomaly explicit. We then study the semiclassical behaviour of the boundary in the N = 24 theory in the presence of an incoming matter wave with a ...
