A Note on the Holographic Beta and C Functions
The holographic RG flow in AdS/CFT correspondence naturally defines a holographic scheme in which the central charge c and the beta function are related by the formula ċ = −2cβaβbG, where Gab is the metric of the kinetic term of the supergravity scalars. In particular, the metric in the space of couplings is fab = 2cGab. We perform some checks of that result and we compare it with the quantum f...
متن کاملCorrelation Functions in Holographic RG Flows
We discuss the computation of correlation functions in holographic RG flows. The method utilizes a recently developed Hamiltonian version of holographic renormalization and it is more efficient than previous methods. A significant simplification concerns the treatment of infinities: instead of performing a general analysis of counterterms, we develop a method where only the contribution of coun...
متن کاملSpectral Functions in Holographic Renormalization Group Flows
The spectrum of two-point functions in a holographic renormalization group flow from an ultraviolet (UV) to an infrared (IR) conformal fixed point is necessarily continuous. For a toy model, the spectral function does not only show the expected UV and IR behaviours, but other interesting features such as sharp peaks and oscillations in the UV. The spectral functions for the SU(3)×U(1) flow in A...
متن کاملProgress on Holographic Three-Point Functions
The gauge/gravity correspondence provides an excellent tool for obtaining relevant information about supersymmetric Yang-Mills (SYM) theories from the study of their dual supergravity backgrounds, which are generated by stacks of D-branes. The most celebrated duality—known as the AdS/CFT correspondence— relates the superconformalN = 4 SYM theory in four dimensions (in the planar limit and at la...
متن کاملHolographic Wave Functions, Meromorphization and Counting Rules
We study the large-Q behavior of the meson form factor FM (Q ) constructed using the holographic light-front wave functions proposed recently by Brodsky and de Teramond. We show that this model can be also obtained within the Migdal’s regularization approach (“meromorphization”), if one applies it to 3-point function for scalar currents made of scalar quarks. We found that the asymptotic 1/Q be...
