Physics 215 A QFT Fall 2017 Assignment

(a) What symmetries do these charges generate (i.e. how do the fields transform)? Show that they are symmetries of S. (b) If you want to, show that [Q, H] = 0, where H is the Hamiltonian. (c) Evaluate [Q, Q]. Hence, non-Abelian. (d) To complete the circle, find the Noether currents J i μ associated to the symmetry transformations you found in part 1a. (e) Generalize to the case of N scalar fields.
