One-loop string corrections for AdS Kaluza-Klein amplitudes

Abstract

Abstract We discuss the string corrections to one-loop amplitudes in AdS5 ×S5, focussing on their expressions in Mellin space. We present the leading (α′)3 corrections to the family of correlators O 2 O 2 O p O p $$ \left\langle {\mathcal{O}}_2{\mathcal{O}}_2{\mathcal{O}}_p{\mathcal{O}}_p\right\rangle $$ at one loop and begin the exploration of the form of correlators with multiple channels. From these correlators we extract some string corrections to one- loop anomalous dimensions of families of operators of low twist.
