$C$-number ignored in charge conjugation
In Weinberg’s QFT V1, under equation 5.5.58, he says that an anticommutator ($c$-number) can be ignored when we exchange spinors, $\psi$ and $\bar{\psi}$. I cannot fully appreciate why we can ignore ...

Time-reversal transformation acts on the Weyl lagrangian with nonabelian gauge field
I would like to show time-reversal transformation acts on the Weyl lagrangian in the familiar 4 dimensional space-time.
My notation follows the same as Peskin QFT book, such as that of chapter 3. I ...

How is a half-odd integer spin field defined in the Wightman axioms?
Can anyone give me a proper definition of 'half-odd integer spin fields' in terms of the Wightman axioms? I'm trying to prove the anti-unitarity of the PCT operator in 'PCT, Spin and Statistics, and ...

Can we build spinorial eigenstates of Time reversal symmetry?
In the SM, and general theories with spinors, we can build the Parity left/right eigenspinors. Indeed, there are also ELKO fields, eigenstates of Charge operator (non-standard Wigner classes). Can we ...

Charge conjugation in Dirac equation
I need to know the mathematical argument about why this relation is true $(C^{-1})^T\gamma ^ \mu C^T = - \gamma ^{\mu T} $ .
Where $C$ is defined by $U=C \gamma^0$ ; $U$= non singular matrix , $T$= ...
