The proceedings presents articles exploring the wide range of physics with can be addressed with measurements using both polarized beams and polarized targets. The conference concentrated on the physics to be done using polarized beams on polarized targets and include selected highlights on advances in the technology. Topics covered include studies of nuclear structure and few-body reactions to test fundamental symmetries, measurements of electromagnetic form factors and of the internal spin structure of nucleons, and tests of QCD.

Experiments using highly polarized intense beams and targets, and theoretical studies of spin and polarization phenomena, are now providing us with numerous additional details of the electroweak and strong interactions and the structure of matter. The spin structure of the nucleon has been measured over wide ranges of kinematic variables, and the cross sections have been calculated to several orders in perturbative field theory. At present, the influence of the higher twist contributions, the gluon spin, and the quark orbital angular momentum are under scrutiny. Quantum chromodynamics (QCD) captures a lot of our experimental knowledge of hard polarized scattering processes. Can our understanding of such processes within QCD be further improved?Hyperons produced in high energy reactions show how puzzling strong interactions between hadrons still are. Spin observables in experiments at intermediate energy are used to test parity and charge symmetries. Will they also reveal, at low energy, a violation of time reversal symmetry? We are on the verge of using parity violation measurements at intermediate electron scattering energies to determine the amount of strange quark contributions to the neutral weak form factor of the nucleon. The polarization of the sea quarks is expected to be measured soon in W± decays produced in high energy polarized proton interactions. Will the jets in polarized Z⁰ decays show a definite handedness? These and many other topics are discussed in these proceedings.

The NEWS99 international symposium discusses symmetries in electroweak processes in nuclei. Many phenomena in nuclear and particle physics are related to symmetry. It is known that we are living in a left-handed world as far as the Weak interaction is concerned, but neutrino physics suggests that a right-handed world may also be relevant. Chiral symmetry and its breaking plays an essential role in generating hadron masses. Symmetries related to flavor in the strong interaction like isospin, SU(3) and so on are known to be violated although they play a crucial role for the understanding of phenomena in nuclear and particle physics. The treatment of tiny breaking is of particular importance. Weak and electromagnetic interactions are well established at the fundamental level and can be used to probe the structure of nuclei and hadrons. A wide variety of phenomena in nuclear and particle physics were discussed in NEWS99 with an emphasis on symmetry. Topics ranged from nuclear structure to neutrino properties,,covering highly phenomenological to fundamental fields.

Major developments have taken place during the last few years in the study of the nuclear paradigm as a result of recent detector and accelerator developments, and of improved theoretical models.The active use of 4-π detectors to measure the gamma decay of excited nuclei has been instrumental in exploring the consequences of extremely high rotational frequencies and excitation energies in the nuclear structure. The identification of superdeformed bands, of limiting temperature for the detection of giant resonances, and of rotational damping, are conspicuous examples of this novel type of research. Studies of the disassembling of the nucleus have been systematically carried out, and the results interpreted in terms of transport models.At even higher temperatures one expects to have a completely new regime of hot dense matter, where the hadronic properties become strongly renormalized by the medium.Furthermore, studies of the properties of the nucleon as a many-body system of quarks and gluons displaying collective degrees of freedom which are damped by couplings to more complicated states, are providing a detailed and consistent picture of the nuclear paradigm.Important progress is also taking place in situations essentially opposite to the scenarios described above, namely in the study of correlations in nuclear matter at very low temperature and density.

Dramatic progress has been made in all branches of physics since the National Research Council's 1986 decadal survey of the field. The Physics in a New Era series explores these advances and looks ahead to future goals. The series includes assessments of the major subfields and reports on several smaller subfields, and preparation has begun on an overview volume on the unity of physics, its relationships to other fields, and its contributions to national needs. Nuclear Physics is the latest volume of the series. The book describes current activity in understanding nuclear structure and symmetries, the behavior of matter at extreme densities, the role of nuclear physics in astrophysics and cosmology, and the instrumentation and facilities used by the field. It makes recommendations on the resources needed for experimental and theoretical advances in the coming decade.
