| contents | In this work, we prove the new factorization pattern for tree-level Yang-Mills (YM) amplitudes proposed in a companion paper. This pattern reveals a decomposition of amplitudes into a sum of gluings of lower-point amplitudes under specific kinematic constraints, making the hidden zeros of YM amplitudes manifest. Utilizing the Cachazo-He-Yuan (CHY) formalism, we rigorously derive these factorizations by systematically analyzing the contributions of singular solutions to the scattering equations. Through the identification and application of key algebraic identities, we demonstrate how cancellations among terms uncover a recursive structure intricately tied to the hidden zeros. This work not only conclusively validates the proposed factorization but also provides new insights into the geometric and algebraic organization of YM amplitudes within the CHY framework. |
