Tests of fundamental symmetries with atoms and molecules

点击翻译按钮获取中文摘要

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.
