Synopsis

The TUCAN(TRIUMF UltraCold Advanced Neutron) collaboration aims to measure the neutron electric dipole moment (nEDM) with the world's highest sensitivity, 10^-27e*cm, which is an order of magnitude better than the current best sensitivity in the world. A nonzero nEDM would shed light on new sources of Charge-Parity violation beyond the Standard Model. The nonzero nEDM has the potential to answer one of the biggest mysteries in the universe, which is the matter-antimatter asymmetry problem, and this also leads us to understand why we exist in the universe. At TRIUMF, the experiment utilizes superfluid Helium(He-II) to produce a high UltraCold Neutron flux, and measures the tiny shift in neutron spin precession by precisely controlling magnetic and electric fields. In this presentation, I will introduce the purpose of the TUCAN nEDM experiment, the process of measuring the nEDM, the current status of the collaboration, and the future prospects to achieve the world's highest sensitivity.
