Workshop on the Search for Baryon and Lepton Number Violations

该提案要求参与者支持计划于2007年9月20日至22日在加州伯克利LBL举行的为期3天的国际研讨会，主题为“寻找重子和轻子数违反”。重子和轻子数的违反已经成为当前超越标准模型的物理学讨论的一个组成部分，特别是与理解中微子的本质、宇宙中物质的起源以及物质和力的可能的大统一有关。研讨会的目标是全面讨论重子(B)和轻子(L)的违反过程，特别是（BL）的违反，作为统一的探测，重子和轻子的发生，左右对称恢复，物质-反物质不对称，无菌物质，镜像物质，暗物质等。这些都与粒子物理中可能出现的新实验观测有关：马约拉纳中微子（20）、质子衰变、中子-反中子振荡、稀有（BaBar和Belle数据）和超子（FNAL超子数据）衰变、-e跃迁、残留中微子、镜像和无菌物质跃迁，以及可能在大型强子对撞机和ILC上揭示的新现象。其中一些新的实验机会可能会在NSF正在创建的新DUSEL实验室中获得。在DUSEL框架下提出的新一代核子衰变、中子振荡和无中微子双β衰变高灵敏度实验，可能有助于阐明标准模型之外的新物理方向，并补充即将进行的对撞机实验所获得的知识。对于更广泛的影响，研讨会将讨论粒子和宇宙学理论，粒子天体物理学，与DUSEL相关的地下实验物理学，核理论以及能量前沿加速器和对撞机数据的新物理学等多学科领域。研讨会将有助于整合现在和未来对超越标准模型的物理学研究的想法，并将为粒子物理学的实验和理论发展揭示新的方向。

The proposal requests participant support for an International 3-day Workshop at LBL Berkeley, CA planned for September 20-22, 2007 with the title "Search for Baryon and Lepton Number Violations".Baryon and Lepton number violation has become an integral part of the current discussions of physics beyond the Standard Model, specifically in connection with understanding the nature of neutrinos, the origin of matter in the Universe, as well as possible Grand Unification of matter and forces. The goal of the Workshop is to have a comprehensive discussion of the Baryon (B) and Lepton (L) violating processes and particularly of (BL) violation as a probe of unification, baryo- and lepto-genesis, Left-Right symmetry restoration, matter-antimatter asymmetry, sterile matter, mirror matter, dark matter etc. These are related to the possible new experimental observations in particle physics: Majorana neutrinos (20), proton decays, neutron-antineutron oscillations, rare (BaBar and Belle data) and hyperon (FNAL hyperon data) decays, -e transitions, relic neutrinos, mirror and sterile matter transitions, and possible new phenomena that can be revealed at LHC and ILC. Some of these new experimental opportunities might become available at the new DUSEL laboratory that is in the process of creation by NSF. New generation of the nucleon decay, neutron oscillations, and neutrinoless double beta decay high-sensitivity experiments, proposed in the framework of DUSEL, might help to throw light on the direction of new physics beyond the Standard Model and supplement the knowledge gained from imminent collider experiments.For the Broader Impacts, the Workshop will address the multidisciplinary fields of particle and cosmology theory, particle astrophysics, underground experimental physics related to DUSEL, nuclear theory, and new physics with accelerator and collider data at the energy frontier. The Workshop will help to integrate the ideas of the present and future searches for physics beyond the Standard Model and will reveal new directions for experimental and theoretical developments in particle physics.
