Note on Permutation Sum of Color-ordered Gluon Amplitudes
Yi-jian Du, Bo Feng, Chih-Hao Fu
In this note we show that under BCFW-deformation the large z behavior of permutation sum of color-ordered gluon amplitudes found by Boels and Isermann in arxiv:1109.5888 can be sim…
Note on Cyclic Sum and Combination Sum of Color-ordered Gluon Amplitudes
Yi-Jian Du, Bo Feng, Chih-Hao Fu
Continuing our previous study \cite{Du:2011se} of permutation sum of color ordered tree amplitudes of gluons, in this note, we prove the large- behavior of their cyclic sum and…
On Primary Relations at Tree-level in String Theory and Field Theory
Qian Ma, Yi-Jian Du, Yi-Xin Chen
By the use of cyclic symmetry, KK relations and BCJ relations, one can reduce the number of independent -point color-ordered tree amplitudes in gauge theory and string theory fr…
BCJ Relation of Color Scalar Theory and KLT Relation of Gauge Theory
Yi-Jian Du, Bo Feng, Chih-Hao Fu
We present a field theoretical proof of the conjectured KLT relation which states that the full tree-level scattering amplitude of gluons can be written as a product of color-order…
