Abstract
Detailed discussions of mass reversal in the quantized field theory are given. The construction of the mass reversal operator M is possible and the explicit form is given. It is shown that the mass reversal operations does not imply the hypothetical reversal of the sign of the intrinsic mass of the elementary particle, but the change of the direction of the intrinsic spin relative to the momentum for the spinor field. One result of this operation on the interaction Hamiltonian is to forbid the mixing of the couplings with and without derivatives for the pion-nucleon interaction. It seems natural to take the mass reversal as a new fundamental invariance (symmetry) principle other than those hitherto investigated.Keywords
