A String Deformation of the Parke-Taylor Factor
Sebastian Mizera, Guojun Zhang
Scattering amplitudes in a range of quantum field theories can be computed using the Cachazo-He-Yuan (CHY) formalism. In theories with colour ordering, the key ingredient is the so…
CHY Loop Integrands from Holomorphic Forms
Humberto Gomez, Sebastian Mizera, Guojun Zhang
Recently, the Cachazo-He-Yuan (CHY) approach for calculating scattering amplitudes has been extended beyond tree level. In this paper, we introduce a way of constructing CHY integr…
Scattering Equations: Real Solutions and Particles on a Line
Freddy Cachazo, Sebastian Mizera, Guojun Zhang
We find -dimensional regions of the space of kinematic invariants, where all the solutions to the scattering equations (the core of the CHY formulation of amplitudes) for…
Minimal Basis in Four Dimensions and Scalar Blocks
Freddy Cachazo, Guojun Zhang
We find a construction that expresses any tree-level -particle color-ordered partial amplitude in gauge theory as a linear combination of a basis of dimension…
New Exact Quantization Condition for Toric Calabi-Yau Geometries
Xin Wang, Guojun Zhang, Min-xin Huang
We propose a new exact quantization condition for a class of quantum mechanical systems derived from local toric Calabi-Yau three-folds. Our proposal includes all contributions to…
One-loop Structure of Higher Rank Wilson Loops in AdS/CFT
Alberto Faraggi, James T. Liu, Leopoldo A. Pando Zayas +1
The half-supersymmetric Wilson loop in SYM is arguably the central non-local operator in the AdS/CFT correspondence. On the field theory side, the vacuum expectation…
