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.

该提案侧重于原子和分子基本对称性测试的理论方面。它具有三个相互关联的组成部分：(i) 原子宇称不守恒 (PNC)、(ii) CP 奇数 (T,P-奇数) 极化率和 (iii) 核反极矩。所有这些项目都是由对超越基本粒子标准模型的新物理学（例如超对称性）的探索驱动的。他们依靠对基本力对原子和分子结构的微小影响的精确实验敏感性。导出的约束是竞争性的，同时也是从粒子对撞机获得的信息的补充。
