“…In order to recover that information, we present here new data where ω → π + π − π 0 . In these data, the polarisation of the ω is determined fully by the normal n to the decay plane of the ω, as explained in an accompanying paper on ωπ 0 and ωηπ 0 final states [3]. Data forpp → ωη have also been reported by Peters [4].…”

These lectures discuss the question of whether a key feature is seen in hadron spectroscopy-the near degeneracy of hadrons with different parity and/or spin. It has been conjectured that this is due to an effective restoration of chiral symmetry. The conjecture is that while these states are, of course, in the symmetry-broken (NambuGoldstone) phase, as one goes higher in the spectrum the states become progressively less sensitive to the dynamics of chiral symmetry breaking. These lectures discuss the current status of this conjecture. The motivations for the conjecture are discussed, as is evidence-both theoretical and experimental-in its favor. Possible alternative explanations for the data are also discussed.

Parity doubling in the meson spectrum

A simple argument for the restoration of parity symmetry high in the hadron spectrum is presented. The restoration scale is estimated to be 2.5 GeV. This in turn implies that typical quark model phenomenology such as scalar confinement or the 3 P0 decay model are only useful for low lying states. Minimal requirements for constructing more general phenomenologies are discussed. An additional mass degeneracy between J ++ and J −− states is shown to occur and an isovector 3 ++ state is predicted at roughly 1700 MeV, in contradiction with the naive quark model. Similarly, isovector and isoscalar 4 −− states are predicted at 2000 MeV. Finally, these results imply that Regge trajectories must become nonlinear at high spin.
