RG Flow , Wilson Loops and the Dilaton Tadpole
نویسنده
چکیده
We discuss the role of the dilaton tadpole in the holographic description of non-supersymmetric gauge theories that are conformal in the planar limit. On the string theory side, the presence of the dilaton tadpole modifies the AdS background inducing a logarithmic running for the radius and the dilaton. Using the holographic prescription we compute the Wilson loop on the gravity side and find a smooth interpolating potential between asymptotic freedom and confinement, as expected from field theory.

Finite-temperature chiral transition in QCD with quarks in the fundamental and adjoint representation
We study the nature of the finite-temperature chiral transition in QCD with N f light quarks in the fundamental and adjoint representation. Universality and renormalization-group (RG) arguments show that the possibility of having a continuous transition is related to the existence of a stable fixed point (FP) in the RG flow of a 3D Landau-Ginzburg-Wilson Φ4 theory with the same chiral symmetry-...

We examine the fixed points to first-order RG flow of a nonlinear sigma model with background metric, dilaton and tachyon fields. We show that on compact target spaces, the existence of fixed points with nonzero tachyon is linked to the sign of the second derivative of the tachyon potential V ′′(T ) (this is the analogue of a result of Bourguignon for the zerotachyon case). For a tachyon potent...

Asymptotically de Sitter dilatonic space-time, holographic RG flow and conformal anomaly from (dilatonic) dS/CFT correspondence ABSTRACT The number of asymptotically de Sitter (non-singular) solutions of 5d dilatonic gravity with positive cosmological constant is found. These solutions are similar to the previously known asymptotically AdS spaces where dilaton may generate the singularity. Usin...
متن کاملFinite-Temperature Gluon Condensate with Renormalization Group Flow Equations
Within a self-consistent proper-time Renormalization Group (RG) approach we investigate an effective QCD trace anomaly realization with dilatons and determine the finite-temperature behavior of the gluon condensate. Fixing the effective model at vanishing temperature to the glueball mass and the bag constant a possible gluonic phase transition is explored in detail. Within the RG framework the ...
متن کاملOn Closed String Tachyon Dynamics
We study the condensation of closed string tachyons as a time-dependent process. In particular, we study tachyons whose wave functions are either space-filling or localized in a compact space, and whose masses are small in string units; our analysis is otherwise general and does not depend on any specific model. Using world-sheet methods, we calculate the equations of motion for the coupled tac...
