An accelerator complex which gives extremely high-intensity proton beams is being constructed in Tokai, Japan. The project is operated by JAEA (Japan Atomic Energy Agency) and KEK (High Energy Accelerator Research Or- nization) and called J-PARC (Japan Proton Accelerator Research Complex). J-PARC accelerator complex consists of 200MeV linac, 3GeV rapid cycling synchrotron, and 30GeV main synchrotron. The energy of linac will be - tendedto400MeVandtheenergyofthemainringwillbeincreasedto50GeV in the near future. J-PARCaimstoperformvariousresearchesoflifeandmaterialsciencesby using neutron beams from the 3GeV rapid cycling synchrotron. J-PARC also aims to perform various particle and nuclear physics experiments by using the 50GeV main synchrotron. In this book we collected several proposals of particle and nuclear physics experiments to be performed by using 50GeV main synchrotron. Prof. Nagamiya gives a brief introduction of J-PARC. He describes the purpose of the project, the aims of the various facilities, and the researches to be done by using these facilities. Prof. Ichikawa discusses about the long baseline nutrino oscillation expe- ment. This proposal is called T2K (Tokai to Kamioka) and it aims to measure mixinganglesintheleptonsector.Theytrytoperformaprecisemeasurement of ? by measuring the ? disappearance.

On the Back Cover
With the imminent operational start of the Japan Proton Accelerator Research Complex (J-PARC), a range of fundamental experiments in nuclear and particle physics will come within reach in the near future, while this new facility will also provide a pulsed neutron source for applications in materials and life sciences.
The present volume is dedicated the detailed presentation of eight among the most promising fundamental experiments, including the study of rare kaon decays (CP and T violations), neutrino oscillations, pentaquarks, hypernuclei precision spectroscopy, muon sciences (g-2, electric dipole moment, flavour violations) and meson studies (mass modification of vector mesons in medium, bound states in nuclei).
This collection of surveys by leading researchers in the field primarily addresses the many postgraduate students and nonspecialists from related areas entering this research over the next few years - they will find this volume an excellent introduction to both the physics and the particular experiments that will be conducted at J-PARC.
