Almost 50 years after the proposal of Lee and Young in 1956 to test the hypothesis of parity violation in weak interactions and the subsequent experimental verification of parity violation by C. S. Wu, parity violation has today become a useful property of weak interactions. This is due to the fact that the focus nowadays has changed: parity violation in weak interactions is no more a topic of investigation but is used as a tool in many different fields ranging from nuclear physics to the search for the hidden extra dimensions requested by string theory. For our first workshop which took place June 5-8, 2002, at the Institut fiir Ke- physik of the Johannes Gutenberg-Universitat Mainz, we concentrated on the in vestigation of the strangeness contribution in the nucleon. This book contains the refereed and selected papers of the second workshop "From Parity Violation to Hadron Structure and more (Part II)", which took place June 8-11, in the Labo- toire de Physique Subatomique et de Cosmologie, in Grenoble. These papers appear in EPJAdirect, the electronic-only part of EPJA, and they are accessible without restrictions. They will also appear in printed form and can be ordered through Springer. The excellent presentations show the dramatic and steady progress in the accuracy of measured parity violating asymmetries over the last few years.

More than 50 years ago, in 1934, Chadwick and Goldhaber (ChG 34) published a paper entitled "A 'Nuclear Photo-effect': Disintegration of the Diplon by -y-Rays."l in the introduction: They noted "By analogy with the excitation and ionisation of atoms by light, one might expect that any complex nucleus should be excited or 'ionised', that is, disintegrated, by -y-rays of suitable energy", and furthermore: "Heavy hydrogen was chosen as the element first to be examined, because the diplon has a small mass defect and also because it is the simplest of all nuclear systems and its properties are as important in nuclear theory as the hydrogen is in atomic theory". Almost at the same time, in 1935, the first theoretical paper on the photodisinte gration of the deuteron entitled "Quantum theory of the diplon" by Bethe and Peierls (BeP 35) appeared. It is not without significance that these two papers mark the be ginning of photonuclear physics in general and emphasize in particular the special role the two-body system has played in nuclear physics since then and still plays. A steady flow of experimental and theoretical papers on deuteron photo disintegration and its inverse reaction, n-p capture, shows the continuing interest in this fundamental process (see fig. 1.1).

For the first time, a complete calculation of all 288 polarization observables of deuteron photodisintegration for polarized photons and an oriented deuteron target is presented for energies below +-production threshold. The observables are calculated within a nonrelativistic framework but with inclusion of lowest-order relativistic effects. Explicit meson exchange currents and isobar configurations as manifestation of subnuclear degrees of freedom are included in the calculation. The sensitivity of the various polarization observables with respect to subnuclear degrees of freedom, to electric and magnetic multipole contributions and to a variety of realistic potential models are systematically investigated. Thus this atlas provides the most detailed and systematic survey on polarization observables of this important process. It allows to analyse the different dynamical properties of the np-system as contained in the various observables and, therefore, will be useful for both theoretical studies and for the planning and evaluation of experiments as well. It serves in addition as an important supplement to the recent general review on deuteron photodisintegration by A. Arenhövel and M. Sanzone (Few-Body Systems, Suppl. 3).

The unique role of strangeness in nuclear physics has recently attracted much attention, from both the theoretical and experimental viewpoints. This is due not only to the broad spectrum of possible hadron many-body systems with strangeness, but also to the fact that strangeness gives us an opportunity to study fundamental baryon-baryon interactions in a new perspective. Our knowledge of this subject has widened as the scope of hypernuclear experiments has expanded from strangeness exchange and the associated production reactions to hypernuclear weak decays, β decays, cascade hypernuclei, double-Λ events, electroproduction of strangeness, etc. This trend will be accelerated by the full operation of new laboratories such as TJLab, COSY, DAΦNE, JHF, MAMI, and others. Various aspects of those important and exciting topics are discussed in this book in order to get a perspective of this fast developing area of nuclear physics.

Giving emphasis on electroweak nuclear interactions the book collects more than 60 papers presented at the 5th International Symposium, Prague, September 1-6, 1991. Further topics covered are: nuclear physics with pions and antiprotons, nuclar physics with strange particles, relativistic nuclear physics, and quark degrees of freedom. They are viewed in their theoretical as well as experimental aspects.
