Integrable open spin chains from flavored ABJM theory

We compute the two-loop anomalous dimension matrix in the scalar sector of planar N = 3 flavored ABJM theory. Using coordinate Bethe ansatz, we obtain the reflection matrices and confirm that the boundary Yang-Baxter equations are satisfied. This establishes the integrability of this theory in the scalar sector at the two-loop order.Natural Science Foundation of China [11425522, 11434013, 11575202, 11475183, 11275207, 11690022, 11305235]; Max-Planck fellowship in Germany; INFN Iniziativa Specifica STFI; Special Fund for Theoretical Physics from NSFC [11447613]SCI(E)ARTICLE
