Ultracold neutrons at TRIUMF: bridging grant for new member

点击翻译按钮获取中文摘要

The matter-antimatter asymmetry in the universe is one of the biggest questions in fundamental physics, as well as philosophy. The neutron electric dipole moment (nEDM) is related to this asymmetry and can thus help shed light on this unsolved puzzle. Experiments searching for the nEDM have also ruled out several particle physics theories over the last five decades. So far, the most stringent limits on the nEDM have been set by experiments using ultracold neutrons; these are so slow that they are reflected by certain wall materials and can subsequently be stored and observed for hundreds of seconds.
