Available in PDF, EPUB and Kindle. Book excerpt: The[pi]N scattering in P[sub 11] channel is investigated within the two-channel model of Pearce and Afnan. The model consists of: (1) vertex interactions b[yields][pi]N, [pi][nabla] with b denoting either a bare nucleon or a bare Roper state, (2) a background potential[upsilon][sub[pi]B, [pi]B] with B= N, [nabla]. Assuming that[upsilon][sub[pi]B, [pi]B] can be phenomenologically parameterized as a separable form and the[pi]N inelasticity can be accounted for by dressing the[nabla] in the[pi][nabla] channel by a[nabla][leftrightarrow][pi]N vertex, it is found that the fit to the P[sub 11] phase shifts up to 1 GeV favors a large mass of the bare Roper state. Our results are consistent with the findings of Pearce and Afnan that if the mass of the bare Roper state is restricted to be[le]1600 MeV, then a physical Roper will have a width which is too narrow causing a rapid variation of the phase shifts at energies near the resonance energy.

Available in PDF, EPUB and Kindle. Book excerpt: Two years ago, at the 12th Winter Workshop on Nuclear Dynamics held here in Snowbird, the authors presented WA80 limits on direct photon production in 200-GeV[sup 32]S+ Au collisions. It was found that the results were consistent (within 1[sigma]) with the absence of an excess of photons over those that can be accounted for by the two-photon decay branches of[pi][sup 0] and[eta] mesons and by the small photon contributions from other radiative decays. They are in the process of finalizing the direct-photon production results from collisions of lead nuclei at 158 GeV/nucleon. The author briefly discusses the status of the analysis and gives some preliminary results at the end of this talk. However, most of this presentation is concerned with a very different aspect of the photon measurements: distributions of neutral pions. In contrast to direct photons which probe initial collision conditions, hadrons, such as neutral pions, interact strongly and decouple late in the reaction evolution and, thus, provide information concerning the system at freeze out. Transverse momentum spectra at low and intermediate p[sub T] relate to thermodynamic and hydrodynamic descriptions of the hot, dense systems. In addition, the high-p[sub T] region reflects the hard-scattering regime and may help one understand initial-state particle production by forming a bridge to proton-proton and proton-nucleus results. It follows that it is essential that the[pi][sup 0] measurements cover a large p[sub T] range.
