In baryon phenomenology we discuss mainly a recent paper paper by G. H. Trilling on SU(3) tests. He shows that SU(3) predictions relating cross sections can be greatly improved by the introduction of angular momentum barrier penetration coefficients, as is already routine when making SU(3) classifications of resonances.Under mesons we discuss ππ and Kπ s‐wave scattering. The recent work of Flatte et al. and of Protopopescu et al. explains s‐wave ππ scattering in terms of two poles: ∈ at s = 600±70 − i(250±50) MeV on sheets II or IV, S* at s = 980± 7 ‐ i(38±7) MeV on sheet II.
