Problem

(a) Using the information in Table 4.6, determine the GG parity of the following mesons: π(140)\pi(140), ρ(770)\rho(770), ω(783)\omega(783), η(549)\eta(549), η′(958)\eta'(958), ϕ(1020)\phi(1020), f(1270)f(1270). (b) Show that R2∣I0⟩=(−1)I∣I0⟩R_2|I0\rangle = (-1)^I|I0\rangle, and use this result to justify equation (4.60).
