A modified Faddeev-Popov path integral density for the quantization of Yang-Mills theory in the Feynman gauge is discussed, where contributions of the Faddeev-Popov ghost fields are replaced by multi-point gauge field interactions. An explicit calculation to O(g(2)) shows the equivalence of the usual Faddeev-Popov scheme and its modified version. (C) 2018 The Authors. Published by Elsevier B.V.
