The research efforts to be carried out will involve various aspects at the interface of particle physics, nuclear physics and astrophysics. General areas of this interface include cosmology, supernova physics and cosmic ray physics. Particular long term projects include refinement of Big Bang nucleosynthesis constraints and predictions, including studies of light element evolution, studies of the quark-hadron transition, nucleochronology, supernova neutrino physics in the light of SN 1987 A, studies of the interplay of particle physics models with galaxy and structure formation,m and implications of the ultra high energy cosmic ray spectrum on physics and astrophysics.

即将开展的研究工作将涉及粒子物理、核物理和天体物理界面的各个方面。这个界面的一般领域包括宇宙学、超新星物理和宇宙射线物理。具体的长期项目包括改进大爆炸核合成的约束和预测，包括轻元素演化的研究，夸克-强子跃迁的研究，核年代学，根据SN 1987 A的超新星中微子物理，粒子物理模型与星系和结构形成的相互作用的研究，超高能宇宙线光谱对物理学和天体物理学的影响。
