Algebraic Consistency and Explicit Construction of One-Loop BCJ Numerators of Yang-Mills and Related Theories
Yi-Jian Du, Chih-Hao Fu, Yihong Wang +1
We study the algebraic structure of one-loop BCJ numerators in Yang-Mills and related theories. Starting from the propagator matrix that connects colour-ordered integrands to numer…

HEFT Numerators from Kinematic Algebra
Chih-Hao Fu, Pierre Vanhove, Yihong Wang
We derive the kinematic numerator factors for heavy-mass effective field theory from the field theory limit of the string theory vertex operator kinematic algebra introduced in arX…
