Form factors with two operator insertions and the principle of maximal transcendentality

Understand

We present the first calculations of two-point two-loop form factors (FFs) with a two identical operators insertion in maximally supersymmetric Yang-Mills theory.

• In this article, we consider the supersymmetry protected half-BPS primary and unprotected Konishi operators.
• Unlike the FFs of a single operator insertion of the half-BPS primary, the FFs involving two half-BPS operators are found to contain lower transcendentality weight terms in addition to the highest ones.
• Moreover, in contrast to Sudakov FFs, the highest weight terms of the FFs of a double half-BPS no longer match with that of a double Konishi.
