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: Synthesizing the theoretical and experimental advances in pion-nucleon interactions over approximately the last twelve years, the authors offer here a timely account of the hadronic interactions of pions and nucleons and of the structure of nucleons. Because of the hadronic SU3 symmetry, the book also treats the structure of baryons in general, and so contains much material external to the specific field of pion-nucleon interactions. Thus the book's subject can be stated as the hadronic structure of baryons as illustrated particularly by pion-nucleon interaction. Following an introductory discussion of isotopic spin, the authors proceed to chapters that treat low energy pion scattering by nucleons and the photoproduction of pions; forward and fixed momentum transfer dispersion relations; analytic properties of scattering amplitudes; formation of nucleon resonances; symmetries and classification of particles and resonances; current algebra, sum rules, and superconvergence relations; scattering at higher energies; pion-nucleon dynamics; pion-nucleon inelastic scattering; and the form factors of the nucleon and the pion. Each chapter is followed by abundant references to the original literature. The level of the writing is suitable for students at the graduate level, and the presentation is even and self-contained. On balance, the authors have prepared a useful consolidation and review of this difficult and changing area of investigation. Originally published in 1973.

Available in PDF, EPUB and Kindle. Book excerpt: One of the most fundamental problems in elementary particle physics is the study of the interaction of the pion meson with nucleons. It is believed that the pion meson plays a fundamental role in the description of nuclear forces and it is important, therefore, to understand the interaction of these particles. The primary method of gaining information on this interaction is through scattering experiments, and this book is concerned primarily with studies of pion-nucleon scattering at high energies.

Available in PDF, EPUB and Kindle. Book excerpt: The pion plays an outstanding role in nuclear physics as a generator of the nuclear force and as an important part of the nuclear many-body problem. At the same time, pion beams are used as probes to explore the nucleus and its interactions. As pion physics has matured over the years, a rich and diverse variety of phenomena has been uncovered. The aim of this book is to examine the underlying physical picture behind these phenomena in a systematic and coherent way. The authors emphasize the interplay between physical concepts and experimental facts more than the formal tools, which are presented in a series of appendices. The book is directed towards advanced students as well as research workers.
