中文摘要
威曼教授将使用原子光学冷却和俘获的新技术来测量碱原子、铯和法郎的放射性同位素的宇称非守恒。在原子宇称非守恒条件下测得的电子-夸克中性电流耦合常数不同于在其他精密电弱测量中探测到的电子-夸克中性电流耦合常数,这一实验对可能存在于标准模型之外的各种新物理具有独特的敏感性。
英文摘要
Professor Wieman will use novel techniques of atomic optical cooling and trapping to measure parity nonconservation in radioactive isotopes of the alkali atoms, cesium and francium. The electron-quark neutral current coupling constants which are measured in atomic parity nonconservation are different from those probed in other precision electroweak measurements, this test is uniquely sensitivity to a variety of new physics which may exist beyond the standard model.
