I will summarize the numerous contributions which were presented in the session Hadronic and Spin Physics, largely dominated by new experimental results.

We analyze the meson spectrum in SU(N c) lattice gauge theory. We use Wilson quarks to measure the pseudoscalar and vector masses in SU(2), SU(3), SU(4) and SU(6), and extrapolate to the large–N c limit. We find that finite–N c corrections are small at all values of the quark mass.

The CP violating Dashen phase in QCD is predicted by chiral perturbation theory to occur when the up-down quark mass difference becomes sufficiently large at fixed down-quark mass. Before reaching this phase, all physical hadronic masses and scattering amplitudes are expected to behave smoothly with the up-quark mass, even as this mass passes through zero. In Euclidean space, the topological su...
