Problem

Draw the Feynman diagrams and write down the amplitudes for the processes γp→π0p\gamma p \to \pi^0 p and γp→K+Σ0\gamma p \to K^+ \Sigma^0 in the SU(3)SU(3) limit, using the meson-baryon Lagrangian density in (3.97). Ignore strong interaction effects in the couplings of the photon. (It is not necessary to actually calculate ∣M∣2|\mathcal{M}|^2.)
