    Graduate Gamma matrices and projection operator question on different representations

    So even in other representations, left-handed and right-handed are defined as (0,1) (1,0) kind of way? (although this is not a rigorous definition)

    Graduate Gamma matrices and projection operator question on different representations

    Typically I understand that projection operators are defined as P_-=\frac{1}{2}(1-\gamma^5) P_+=\frac{1}{2}(1+\gamma^5) where typically also the fifth gamma matrices are defined as \gamma^5=i\gamma^0\gamma^1\gamma^2\gamma^3 and.. as we choose different representations the projection...
