Gamma 5 dirac matrice

    Hi, i wonder somethin'

    when I see that definition of the matrice:
    I don't see why it is a pseudo-scalar.

    If you inspect [tex]\gamma^5[/tex],you can see that it anti commutes with [tex]\gamma^0[/tex] (while 0 stands for the time coordinate).
    so under space inversion the expression will change it's sign
    and that is a property of a Pseudoscalar
