Chiral projection operator
WebApr 14, 2024 · I have a doubt in using the chiral projection operators. In principle, it should be ##P_L \psi = \psi_L##. $$ P_L = \frac{1-\gamma^5}{2} = \frac{1}{2} … WebThus this operator exchanges the chirality of the chiral projections of the complex-self-conjugate spinor, and it transforms leftinto right-handed states and vice versa, a virtue which is essentially associated with the spin flip operator defining. In conclusion, in this special situation the operator acts as chirality conjugation or reversal ...
