In the standard QFT textbook, the Hermitian conjugate of a Dirac field bilinear(adsbygoogle = window.adsbygoogle || []).push({});

[itex]\bar\psi_1\gamma^\mu \psi_2[/itex] is [itex]\bar\psi_2\gamma^\mu \psi_1[/itex].

Here is the question, why there is not an extra minus sign coming from the anti-symmetry of fermion fields?
