Carlos Andrés Cardona (IAFE, UBA)
Worldsheet correlation functions in AdS3/CFT2
One of the simplest realizations of the AdS/CFT duality, is the one
relating type IIB string theory in AdS3xS3xT4 with some two-dimensional
SCFT on the symmetric product of N copies of T4. In this talk we will
review some recent test of this duality through the comparison of
correlation functions in both sides of the correspondence. We shall mainly
discuss four-point functions in small cross-ratios, where we found some
slight evidence of a possible extension of the non-renormalization
theorem.

Two-point correlators of R-symmetry currents at finite ‘t Hooft coupling
I will discuss on the role of two-point correlation functions of
R-symmetry currents in the holographic dual description of supersymmetric
plasmas at low and high momentum regimes. I will focuss on the leading
finite ‘t Hooft coupling corrections to the correlators, obtained from
\alpha’^3 string theory corrections to type IIB supergravity. In the
hydrodynamical regime I will show results on the plasma conductivity. On
the other hand, at large momentum I will discuss about implications on
deep inelastic scattering.
