The research of this group of theoretical high energy physicists at Harvard University consists of: (a) the appli- cation of quantum field theory to a variety of current problems in particle physics; (b) the application of astrophysical data and cosmological constraints to particle physics, and (c) an investigation of the properties of the "string theory" of ele- mentary particles. Subjects to be addressed in (a) include: symmetry breaking and "flavor" interactions; grand unification; quantum chromodynamics; and semiclassical effects in field theory. Subjects to be addressed in (b) include: neutrino masses and mixing; galaxy formation; and inflation. Subjects to be addressed in (c) include: connections between string theory and developing fields of mathematics and mathematical physics; search for new insights into formal properties of quantum field theory; new mathematical structures of potential use in physics; unexpected answers to questions that have been intractable in the standard effective field theory context.

哈佛大学这群理论高能物理学家的研究包括：(A)量子场论在粒子物理中的各种当前问题中的应用；(B)天体物理数据和宇宙学约束在粒子物理中的应用；(C)基本粒子“弦理论”的性质的研究。将在(A)中讨论的主题包括：对称破缺和“味道”相互作用；大统一；量子色动力学；以及场论中的半经典效应。(B)中要讨论的主题包括：中微子质量和混合；星系形成；以及暴涨。(C)中要讨论的主题包括：弦理论与数学和数学物理发展领域之间的联系；对量子场论形式性质的新见解；潜在用于物理的新的数学结构；在标准有效场论背景下一直难以解决的问题的意外答案。
