ABJM θ-Bremsstrahlung at four loops and beyond

Year: 2017

Type: article

Abstract: In ABJ(M) theory a generalized cusp can be constructed out of the 1/6-BPS Wilson line by introducing an angle φ in the spacial contour and/or an angle θ in the internal R-symmetry space. The small angles limits of its anomalous dimension are controlled by corresponding Bremsstrahlung functions. In this note we compute the internal space θ-Bremsstrahlung function to four loops at weak coupling in the planar limit. Based on this result, we propose an all order conjecture for the θ-Bremsstrahlung function.
