BCJ, worldsheet quantum algebra and KZ equations
Chih-Hao Fu, Yihong Wang
We exploit the correspondence between twisted homology and quantum group to construct an algebra explanation of the open string kinematic numerator. In this setting the representat…
A Vertex Operator Algebra Construction of the Colour-Kinematics Dual numerator
Chih-Hao Fu, Pierre Vanhove, Yihong Wang
We derive a vertex operator based expression for the kinematic numerators of Yang-Mills amplitudes by applying the momentum kernel formalism to open string amplitudes. The expressi…
The MHV lagrangian vertices and the Parke-Taylor formula
Chih-Hao Fu
We explicitly calculate the vertices of the MHV-rules lagrangian in 4-dimensions. This proves that the vertices in the lagrangian obtained by a canonical transformation from light-…
S-matrix equivalence restored
Chih-Hao Fu, Jonathan Fudger, Paul R. W. Mansfield +2
The canonical transformation that maps light-cone Yang-Mills theory to a Lagrangian description of the MHV rules is non-local, consequently the two sets of fields do not necessaril…
