[QUE/QFT-06007] QFT-PROBLEM

Show that under time reversal \(\bar{u}(p) \to u(—p)B \) and \(v(p) \to \bar{v}(—p) B\). Use this to show that under \(P T\) together \[\bar{u}(p{'}) \gamma_{\alpha_1} \gamma_{\alpha_2}\ldots \gamma_{\alpha_n} u(p) \to \bar{u}(p)\gamma_{\alpha_n}\gamma_{\alpha_{n-1}}\ldots \gamma_{\alpha_1} u(p{'}) \]
