This proposal focuses on theoretical aspects of tests of fundamental symmetries withatoms and molecules. It has three interrelated components: (i) atomic parity nonconservation (PNC), (ii) CP-odd (T,P-odd) polarizabilities, and (iii) nuclear anapolemoments. All these projects are driven by searches for new physics, such assupersymmetry, beyond the standard model of elementary particles. They rely onexquisite experimental sensitivity to minute effects of fundamental forces on atomic andmolecular structure. The derived constraints are competitive and, at the same time,complementary to the information gained from particle colliders.

这个建议集中在理论方面的测试基本对称性与原子和分子。它有三个相互关联的组成部分：（i）原子宇称不守恒（PNC），（ii）CP-奇（T，P-odd）极化率，和（iii）核反动量。所有这些项目都是为了寻找新的物理学，比如超越基本粒子标准模型的超对称性。他们依赖于对原子和分子结构上基本力的微小影响的实验灵敏度。导出的约束是竞争性的，同时，补充粒子对撞机获得的信息。
