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…
On a CFT limit of planar -deformed SYM theory
Christoph Sieg, Matthias Wilhelm
We show that an integrable four-dimensional non-unitary field theory that was recently proposed as a certain limit of the -deformed SYM theory is incomplete an…
On-Shell Methods for the Two-Loop Dilatation Operator and Finite Remainders
Florian Loebbert, Dhritiman Nandan, Christoph Sieg +2
We compute the two-loop minimal form factors of all operators in the SU(2) sector of planar N=4 SYM theory via on-shell unitarity methods. From the UV divergence of this result, we…
Cutting through form factors and cross sections of non-protected operators in N=4 SYM
Dhritiman Nandan, Christoph Sieg, Matthias Wilhelm +1
We study the form factors of the Konishi operator, the prime example of non-protected operators in N=4 SYM theory, via the on-shell unitarity methods. Since the Konishi operator is…
A piece of cake: the ground-state energies in gamma_i-deformed N=4 SYM theory
Jan Fokken, Christoph Sieg, Matthias Wilhelm
In the non-supersymmetric gamma_i-deformed N=4 SYM theory, the scaling dimensions of the operators tr[Z^L] composed of L scalar fields Z receive finite-size wrapping and prewrappin…
The spectrum of tachyons in AdS/CFT
Zoltan Bajnok, Nadav Drukker, Arpad Hegedus +4
We analyze the spectrum of open strings stretched between a D-brane and an anti-D-brane in planar AdS/CFT using various tools. We focus on open strings ending on two giant graviton…
