Theoretical predictions of new long-range forces have arisen in many contexts. Gravitational strength effects play an especially important role in modern theories which attempt to unify gravity with the other forces. Most recently, Dimopoulos and Giudice and have argued that the moduli of string theory may give rise to a large number of new long- ranges forces of roughly gravitational strength, with ranges within the experimentally accessible region. The investigators will undertake a search for new gravitational strength forces below 1 cm. The experiment will be sensitive to a Yukawa force of gravitational strength with a range between 50 micro meters and 1 cm, and it will set new limits on stronger forces with ranges as small as 10 micro meters. Almost all of the remaining parameter space for the moduli forces associated with the light quarks and the gluon as predicted by Dimopoulos and Giudice will be explored.

关于新的远程作用力的理论预测在许多情况下都出现了。引力强度效应在试图将引力与其他力统一起来的现代理论中扮演着特别重要的角色。最近，迪莫普洛斯和朱迪斯认为，弦理论的模数可能会产生大量新的长程引力，其范围在实验上可以到达的区域内。调查人员将在1厘米以下寻找新的引力力量。这项实验将对范围在50微米到1厘米之间的汤川力很敏感，并将对范围小至10微米的更强的力设定新的限制。正如Dimopoulos和Giudice预测的那样，几乎所有与轻夸克和胶子相关的模量力的剩余参数空间都将被探索。
