Research in theoretical elementary particle physics will focus on theproperties of nuclear matter in extreme environments, such as hightemperatures or high density. Phase transitions are expected in thesesituations between conventional matter approximating the interior of alarge nucleus and new, highly exotic large-scale states of matter in whichthere may be superfluidity, superconductivity and plasmas of unconfinedquarks and gluons, the constituents of nuclear matter. Computersimulations as well as precise, analytic methods based on the theory ofsymmetries, will be employed to search for these new phenomena. Thesestudies are important because they may tell us about conditions in theearly universe.

理论基本粒子物理学的研究将集中于极端环境（例如高温或高密度）下核物质的特性。在接近大核内部的常规物质和新的、高度奇异的大尺度物质状态之间的这些情况下，预计会发生相变，其中可能存在超流性、超导性以及无约束夸克和胶子（核物质的成分）的等离子体。计算机模拟以及基于对称理论的精确分析方法将被用来寻找这些新现象。这些研究很重要，因为它们可能告诉我们早期宇宙的状况。
