Book Description
The G0 experiment in Hall C at Jefferson Lab measures the parity-violating asymmetry in elastic electron scattering off hydrogen and quasielastic electron scattering off deuterium in the Q2 range from 0.1 to 1 (GeV)2 in both forward and backward running modes by using a longitudinally polarized electron beam on unpolarized liquid targets. By measuring three independent asymmetries, one in forward running mode off liquid hydrogen and two in backward running mode, one off liquid hydrogen and one off liquid deuterium, the experiment aims to perform for the first time a complete separation and mapping of the strange vector form factors of the nucleon (G_Ms, G_Es) and the isovector axial form factor (G_Ae(T=1)) in three Q2 bins over the Q2 range from 0.1 to 1 (GeV/c)2. To complete the physics program in both forward and backward modes it will take about five years. To accomplish the forward running mode program some 100 C of data are needed. This thesis is based on 9 C of physics data taken during the first chekout of the G0 apparatus during October 2002 - January 2003.

Book Description
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.

Book Description
The results from the G0 forward angle experiment are reported in this talk. The parity-violating asymmetry of elastic e-p scattering has been measured within the range of the four-momentum transfer (Q2) from 0.12 to 1.0 (GeV/c)2, which yields linear combinations of the strange electric and magnetic form factors of the nucleon, G{sub E}{sup s} + etaG{sub M}{sup s}, in the same Q2 range. The G0 results, combined with the measurements from other experiments, indicate that G{sub E}{sup s} and G{sub M}{sup s} are both likely non-zero.

Book Description
This book contains the proceedings of the third international workshop on From Parity Violation to Hadronic Structure and More. The many applications of parity violation are way beyond the scope of what Lee and Yang could have imagined fifty years after their proposal. For the physics topics discussed during this workshop, the application of parity violation has become a standard work horse allowing for the extraction of many physics topics in different experiments.

Book Description
The SPIN 2002 Proceedings describe the recent advances in the field of spin physics. The topics cover research in high energy and nuclear physics and the study of the nuclear spin structure. The symposium also covers advances in polarized proton and electron acceleration and storage as well as polarized ion sources and targets. The first measurement of spin physics observables in pp collisions at center of mass energy of 200 Gev was announced at this symposium.
