U.S. - France Cooperative Research: String Theory and M-Theory Applied to Particle Physics and Cosmology

9910077-该美法合作研究奖支持村山仁博士和玛丽·K·盖拉德博士以及加州大学伯克利分校的一些研究生，他们与法国巴黎第十一大学理论物理实验室的埃米利安·杜达斯和皮埃尔·贝内特鲁伊合作。由该奖项资助的弦理论和M(膜)理论的国际合作将集中在(1)弦理论和有效场论中的超对称破缺；(2)弦派生的有效理论的构建及其对粒子现象学的影响；以及(3)弦和M理论的宇宙学方面。理论研究将为LEP、费米实验室、大型强子对撞机和未来的轻子对撞机的实验以及高能物理和宇宙学的实验提供信息。超弦理论和膜等基本扩展物体的相关理论，为建立涵盖所有粒子相互作用的量子引力理论提供了希望。这些调查的最终目标是确定这些理论的后果，随后通过观测和高能物理实验进行验证。伯克利小组为这次合作带来了在超弦模型、有效场论以及超对称和大统一模型方面的广泛专业知识。此外，奥赛团队在弦论、量子引力和宇宙学方面的专业知识也起到了补充作用。美国和法国的研究人员，特别是项目中的研究生，将从彼此以及与位于伯克利和奥赛校园的其他弦理论家、理论宇宙学家和天体物理学家的互动中受益。

9910077MurayamaThis U.S.-France cooperative research award supports Drs. Hitoshi Murayama and Mary K. Gaillard and some graduate students from the University of California at Berkeley in a collaboration with Emilian Dudas and Pierre Benetruy of the Theoretical Physics Laboratory, University of Paris XI, Orsay, France. The international collaboration funded by this award in string theory and M- (membrane) theory will focus on (1) supersymmetry breaking in string theory and in effective field theories; (2) construction of string-derived effective theories and their consequences for particle phenomenology; and (3) cosmological aspects of strings and M-theory. The theoretical investigations will provide information for experiments at the LEP, Fermilab, Large Hadron Collider and future lepton colliders, and experiments in high-energy physics and cosmology. Superstring theory and related theories with elementary extended objects, like membranes, offer the promise for a quantum theory of gravity that encompasses all particle interactions. The ultimate goal of these investigations is to determine the consequences of these theories, subsequently tested by observations and high-energy physics experiments. The Berkeley group brings to this collaboration extensive expertise in superstring models, effective field theories, and the supersymmetric and grand unified model. This is complemented by the Orsay group's expertise in string theory, quantum gravity, and cosmology. The U.S. and French investigators, in particular, the graduate students in the project, will benefit from interaction with each other and with other string theorists, theoretical cosmologists, and astrophysicists located on the Berkeley and Orsay campuses.
