Abstract:
In a string calculation to order , we compute an eight-derivative four-dilaton term in the type IIB effective action. Following the AdS prescription, we compute the order correction to the four-point correlation function involving the operator in four dimensional N=4 super Yang-Mills using the string corrected type IIB action extending the work of Freedman et al. (hep-th/9808006). In the limit where two of the Yang-Mills operators approach each other, we find that our correction to the four-point correlation functions develops a logarithmic singularity. We discuss the possible cancellation of this logarithmic singularities by conjecturing new terms in the type IIB effective action.Note:
