Discontinuity relations for the AdS(4)/CFT(3) correspondence

Understand

We study in detail the analytic properties of the Thermodynamic Bethe Ansatz (TBA) equations for the anomalous dimensions of composite operators in the planar limit of the 3D N=6 superconformal Chern-Simons gauge theory and derive functional relations for the jump discontinuities across the branch cuts in the complex rapidity plane.

• These relations encode the analytic structure of the Y functions and are extremely similar to the ones obtained for the previously-studied AdS(5)/CFT(4) case.
• Together with the Y-system and more basic analyticity conditions, they are completely equivalent to the TBA equations.
• We expect these results to be useful to derive alternative nonlinear integral equations for the AdS(4)/CFT(3) spectrum.
