Abstract: The authors claim to have found a -proper- -gauge-invariant- definition of acharged-particle-s momentum in gauge theory, which is more -superior- than thetextbook version. I show that their result arises from a misunderstanding ofgauge symmetry by generalizing the Coulomb gauge result indiscriminately and isnot physical.
