This proposal together with six other proposals in priority area B addresses a number of questions which are at the forefront of particle physics, with main emphasis on the search for new physics beyond the Standard Model of particles physics, and in particular, on the question of unification of all forces shortly after the Big Bang. This grand unification is not part of the Standard Model, and new symmetry concepts are needed like left-right symmetry, fundamental fermion compositeness, new particles, leptoquarks, supersymmetry, and many more. Precise symmetry tests of various kinds are coming within reach with the proposed facility PERC, where count rates of neutron decay products are increased by a factor 100 compared to best experiments. Our goal is ß spectroscopy, where the spectra and angular distributions of the emerging decay particles will be distortion-free on the level of 10−4.

该提案与优先领域B的其他六项提案一起，涉及粒子物理学前沿的若干问题，主要侧重于在粒子物理学标准模型之外寻找新的物理学，特别是大爆炸后不久所有力的统一问题。这种大统一不是标准模型的一部分，需要新的对称性概念，如左右对称性，基本费米子复合性，新粒子，leptoquark，超对称性等等。各种精确的对称性测试即将达到与拟议的设施PERC，中子衰变产物的计数率增加了100倍，最好的实验相比。我们的目标是能谱学，其中出现的衰变粒子的光谱和角分布在10−4的水平上是无畸变的。
