A note on NMHV form factors from the Graßmannian and the twistor string
David Meidinger, Dhritiman Nandan, Brenda Penante +1
In this note we investigate Graßmannian formulas for form factors of the chiral part of the stress-tensor multiplet in superconformal Yang-Mills theory. We present…
Evaluation of the operatorial Q-system for non-compact super spin chains
Rouven Frassek, Christian Marboe, David Meidinger
We present an approach to evaluate the full operatorial Q-system of all -invariant spin chains with representations of Jordan-Schwinger type. In particular,…
Yangian-type symmetries of non-planar leading singularities
Rouven Frassek, David Meidinger
We take up the study of integrable structures behind non-planar contributions to scattering amplitudes in N=4 super Yang-Mills theory. Focusing on leading singularities, we derive…
On-shell Diagrams, Graßmannians and Integrability for Form Factors
Rouven Frassek, David Meidinger, Dhritiman Nandan +1
We apply on-shell and integrability methods that have been developed in the context of scattering amplitudes in N=4 SYM theory to tree-level form factors of this theory. Focussing…
Dynamic Lattice Supersymmetry in gl(n|m) Spin Chains
David Meidinger, Vladimir Mitev
Supersymmetry operators that change a spin chain's length have appeared in numerous contexts, ranging from the AdS/CFT correspondence to statistical mechanics models. In this artic…
