Review of AdS/CFT Integrability, Chapter III.2: Exact world-sheet S-matrix
Changrim Ahn, Rafael I. Nepomechie
We review the derivation of the S-matrix for planar N=4 supersymmetric Yang-Mills theory and type IIB superstring theory on an AdS5xS5 background. After deriving the S-matrix for t…
Review of AdS/CFT Integrability: An Overview
Niklas Beisert, Changrim Ahn, Luis F. Alday +23
This is the introductory chapter of a review collection on integrability in the context of the AdS/CFT correspondence. In the collection we present an overview of the achievements…
Higher Equations of Motion in N=2 Superconformal Liouville Field Theory
Changrim Ahn, Marian Stanishkov, Mihail Stoilov
We present an infinite set of higher equations of motion in N=2 supersymmetric Liouville field theory. They are in one to one correspondence with the degenerate representations and…
Twisted Bethe equations from a twisted S-matrix
Changrim Ahn, Zoltan Bajnok, Diego Bombardelli +1
All-loop asymptotic Bethe equations for a 3-parameter deformation of AdS5/CFT4 have been proposed by Beisert and Roiban. We propose a Drinfeld twist of the AdS5/CFT4 S-matrix, toge…
Quantum finite-size effects for dyonic magnons in the AdS_4 x CP^3
Changrim Ahn, Minkyoo Kim, Bum-Hoon Lee
We compute quantum corrections to finite-size effects for various dyonic giant magnons in the AdS_4 x CP^3 in two different approaches. The off-shell algebraic curve method is used…
Finite-size effect for four-loop Konishi of the beta-deformed N=4 SYM
Changrim Ahn, Zoltan Bajnok, Diego Bombardelli +1
We propose that certain twists of the su(2|2) S-matrix elements describe the beta-deformation of N=4 supersymmetric Yang-Mills theory. We compute the perturbative four-loop anomalo…
