The research will focus on three aspects of non- accelerator particle physics: 1) A large balloon-borne experiment (EXAM) will be used to search for evidence of large scale quantities of antimatter in the universe. Data from a 1988 flight will be analyzed and at least one additional fight will be made. 2) The world's largest underground particle detector (MACRO) currently being constructed in Italy will be used to search for monopoles and study cosmic ray neutrinos and muons. 3) Cryogenic detectors will be developed to search, at high levels of sensitivity, for dark matter, the so called "missing mass" of the universe. This work will be done by scientists from Boston University in collaboration with scientists from other institutions.

研究将集中在非加速器粒子物理的三个方面：1)大型气球实验（EXAM）将用于寻找宇宙中大量反物质的证据。将分析1988年一次飞行的数据，并至少再进行一次飞行。2)目前正在意大利建造的世界上最大的地下粒子探测器（MACRO）将用于寻找单极子和研究宇宙射线中微子和μ子。低温探测器将被开发出来，以高灵敏度搜索暗物质，即宇宙中所谓的“缺失质量”。这项工作将由波士顿大学的科学家与其他机构的科学家合作完成。
