Unformatted text preview: x 1-direction as L = e i K 1 L with K 1 =-i 1 2 (and similarly for L ). Show that 0 L a L = L a L for a = 2 , 3, so these have the right property to be the 2- and 3-components of a 4-vector. (4) Show that, if L and R are left- and right-handed spinors, respectively, then 2 * L and 2 * R transform as right- and left-handed spinors, respectively. 1...
