Evaluation of the CHY Gauge Amplitude

C. S. Lam, York-Peng Yao

The Cachazo-He-Yuan (CHY) formula for -gluon scattering is known to give the same amplitude as the one obtained from Feynman diagrams, though the former contains neither vertice…

The Role of Möbius Constants and Scattering Functions in CHY Scalar Amplitudes

C. S. Lam, York-Peng Yao

The integrations leading to the Cachazo-He-Yuan (CHY) double-color -point massless scalar amplitude are carried out one integral at a time. Möbius invariance dictates the final…

Off-Shell CHY Amplitudes

C. S. Lam, York-Peng Yao

The Cachazo-He-Yuan (CHY) formula for on-shell scattering amplitudes are extended off-shell. The off-shell amplitudes are Möbius invariant, and have the same momentum poles as the…

Color kinematic symmetric (BCJ) numerators in a light-like gauge

Diana Vaman, York-Peng Yao

Color-ordered tree level scattering amplitudes in Yang-Mills theories can be written as a sum over terms which display the various propagator poles of Feynman diagrams. The numerat…

Analytic Scattering Amplitudes for QCD

Diana Vaman, York-Peng Yao

By analytically continuing QCD scattering amplitudes through specific complexified momenta, one can study and learn about the nature and the consequences of factorization and unita…
