A primary field in Conformal Field Theory transforms as
ϕ(z,ˉz)=(dzdz′)h(dˉzdˉz′)ˉhϕ(z′,ˉz′)
under a conformal transformation.
I read in chapter 2 page 41 in Strings, Conformal Fields and M-theory by M.Kaku that h+ˉh is called a conformal weight and h−ˉh a conformal spin.
What is the motivation, especially for the spin-one, for these names?
