Abstract [en]

We calculate the colour-ordered form factor for chiral primary operators built from J scalar fields of ABJ(M) theory to J scalar final states. We work in the 't Hooft limit and show that the leading quantum correction is O(lambda(2)), where lambda is the 't Hooft coupling. We evaluate this leading correction using standard Feynman diagrams and dimensional regularization, and find that the leading divergence is 1/epsilon(2) where the spacetime dimension is d = 3 - 2 epsilon. We further find that the result respects maximal transcendentality.
