1211.5838 (Bogeun Gwak et al.)

Correlation functions of the ABJM model    [PDF]

Bogeun Gwak, Bum-Hoon Lee, Chanyong Park
In the ABJM model, we study the two point function of various solitonic strings and the three point functions with a marginal or (ir)relevant scalar operator by using the AdS/CFT correspondence. After explicitly calculating these quantities, we show that the string results are perfectly consistent with the RG analysis of the dual gauge theory. Especially, for the circular string wrapped in \phi_1 we find a new size effect like the finite size effect of the magnon, which may describe the size effect of the closed spin chain. Finally, we calculate the three point function with an (ir)relevant scalar operator, which is closely related to that with a marginal operator.
