Note on symmetric BCJ numerator
Chih-Hao Fu, Yi-Jian Du, Bo Feng · Journal of High Energy Physics · 2014
We present an algorithm that leads to BCJ numerators satisfying manifestly the three properties proposed by Broedel and Carrasco in [42]. We explicitly calculate the numerators at 4, 5 and 6-points and show that the relabeling property is generically satisfied.
