On Form Factors and Correlation Functions in Twistor Space
Laura Koster, Vladimir Mitev, Matthias Staudacher +1
In this paper, we continue our study of form factors and correlation functions of gauge-invariant local composite operators in the twistor-space formulation of N=4 super Yang-Mills…
A Quantum Check of AdS/dCFT
Isak Buhl-Mortensen, Marius de Leeuw, Asger C. Ipsen +2
We build the framework for performing loop computations in the defect version of N=4 super Yang-Mills theory which is dual to the probe D5-D3 brane system with background gauge-fie…
Two-Loop SL(2) Form Factors and Maximal Transcendentality
Florian Loebbert, Christoph Sieg, Matthias Wilhelm +1
Form factors of composite operators in the SL(2) sector of N=4 SYM theory are studied up to two loops via the on-shell unitarity method. The non-compactness of this subsector impli…
One-loop Wilson loops and the particle-interface potential in AdS/dCFT
Marius de Leeuw, Asger C. Ipsen, Charlotte Kristjansen +1
We initiate the calculation of quantum corrections to Wilson loops in a class of four-dimensional defect conformal field theories with vacuum expectation values based on N=4 super…
Renormalization group coefficients and the S-matrix
Simon Caron-Huot, Matthias Wilhelm
We show how to use on-shell unitarity methods to calculate renormalization group coefficients such as beta functions and anomalous dimensions. The central objects are the form fact…
One-loop one-point functions in gauge-gravity dualities with defects
Isak Buhl-Mortensen, Marius de Leeuw, Asger C. Ipsen +2
We initiate the calculation of loop corrections to correlation functions in 4D defect CFTs. More precisely, we consider N=4 SYM with a codimension-one defect separating two regions…
