Abstract:
Muon dipole moments, anomalous magnetic moment (g-2) and electric dipole moment (EDM) offers unique ways to explore physics beyond the standard model via quantum loops. We are preparing for a new experiment to measure g-2 and EDM of positive muon at J-PARC. The experiment relies on high intensity proton beam provided at J-PARC and novel technologies of muon cooling and acceleration to obtain low-emittance muon beam. Such a beam allows measurement of muon spin precession in a well-controlled compact magnetic storage ring. Recently, we demonstrated acceleration of positive muons from 25 meV to 100 keV for the first time in the world. In this seminar, I would like to overview the recent progress of the experiment and key technologies behind the success of the muon acceleration.
Biography:
Prof. Tsutomu Mibe is a senior scientist at IPNS, KEK, leading research in Muon g-2 and electric dipole moment (EDM) experiments. His primary focus is on precise measurements of the muon's anomalous magnetic moment and EDM, aiming to uncover potential signs of new physics beyond the Standard Model. Mibe collaborates with leading experts to explore how the advanced technologies developed for the Muon g-2/EDM experiments can be leveraged for other applications, including the development of future muon colliders. In addition, he is involved in cutting-edge research using quantum sensors to design novel particle physics experiments.
