Recently, Arkani-Hamed et al. proposed the existence of zeros in scattering amplitudes certain quantum field theories including cubic adjoint scalar theory Tr($\phi^3$), $SU(N)$ non-linear sigma model (NLSM) and Yang-Mills (YM) theory. These hidden are special kinematic points where amplitude vanishes factorizes into a product lower-point amplitudes, similar to factorization near poles. In this letter, we show close connection between such color-kinematics duality. fact, all can be derived from Bern-Carrasco-Johansson (BCJ) relations. We also that these extend via Kawai-Lewellen-Tye (KLT) relations Galileon their corrections, evincing present permutation-invariant amplitudes.
