Description
----------------------------------------
＃14 Pioneer project seminar
---------------------------------------
http://e3project.riken.jp/seminar/index.html
Speaker: Prof. Bhanu Pratap Das
Title: Electric Dipole Moment of the Electron: Probe of New Physics Beyond the Standard Model
Affiliation: Tokyo Institute of Technology
Schedule: Fri. 11th September 2015 (11:00-12:00)
Place: Main research building, 5th floor, 535,537
Language: English
Abstract:
The observation of a permanent electric dipole moment (EDM) of a physical system is a signature of the simultaneous violations of parity (P) and time-reversal (T) symmetries. T violation implies the violation of the combined symmetries of charge conjugation and parity;i.e. CP violation via the CPT theorem. The origin of CP violation is still not well understood. This phenomenon has only been observed in the K and B mesons, and the results are essentially in agreement with the predictions of Kobayashi and Maskawa in the framework of the standard model of particle physics. However, this model cannot explain the matter-antimatter asymmetry in the universe for which CP violation is a prerequisite. In addition, its prediction of the electron EDM is several orders of magnitude below its current limit. Indeed the electron EDMs is an excellent probe of new physics beyond the standard model.
The talk will focus on the EDM of the electron. After touching upon the connection of the electron EDM with the standard model, its manifestation in atoms and molecules will be highlighted. The symbiotic relationship between atomic/molecular theory and experiment in determining the electron EDM will be emphasised. The present status and the future prospects of the search for the electron EDM will be presented and their implications for physics beyond the standard model will be discussed.
