The existence of a nonzero permanent electric dipole moment (EDM) of a non-degenerate<\/i><\/p>\n
physical system physical system is a signature of the simultaneous violations of time-reversal<\/i><\/p>\n
(T) and parity (P) symmetries. T violation implies the combined charge conjugation (C) and<\/i><\/p>\n
P violation (CP violation) via the CPT theorem.<\/i><\/p>\n
Atomic EDMs are excellent probes of physics beyond the standard model , and they provide<\/i><\/p>\n
important insights into a rich variety of CP violations – leptonic, semi-leptonic, and hadronic<\/i><\/p>\n
sectors. Experimental searches are underway for the EDMs of paramagnetic (open-shell) and<\/i><\/p>\n
diamagnetic (closed-shell) atoms. The results of the experiments can be combined with those<\/i><\/p>\n
of sophisticated atomic many-body calculations to determine various CP violating coupling<\/i><\/p>\n
constants at the atomic level. These quantities can ultimately be related to the CP violation<\/i><\/p>\n
parameters at the elementary particle level and tested with the predictions of the different<\/i><\/p>\n
particle physics models.<\/i><\/p>\n
The present talk will give an introduction to atomic EDMs and touch upon on some of the<\/i><\/p>\n
ongoing searches of these EDMs as well as their future prospects.<\/i><\/p>\n","protected":false},"featured_media":0,"template":"","tags":[],"seminar_category":[53],"acf":{"s_now_accepting":true,"s_date_order":"2012-05-15 17:00:00","s_date_end":null,"s_date_text":"","s_text":"Bhanu Pratap Das","s_place":"Lecture Room (ES034)","s_place_other":"","s_categoryother":"EHQG\/Tau lepton\/KMI-theory seminar","s_poster":"
