Title: Towards Witten Diagrams at one-loop in AdS

Abstract: In this talk we consider Witten diagrams at one loop in AdS space for scalar theories. I will present the Mellin representation for some tree-level and one-loop bubble corrections to the four-point correlation function of conformal field theories with gravity dual.  For the case corresponding to the four-particles triangle and  four-particles box, we present the results up to an integration over the Schwinger parameters corresponding to the propagators of the internal particles running into the loop. We then discuss an approach to deal with those integrals.
