TRIUMF seminars: GAPS Coffee chats

[Gaps]

Hi GAPS Community!

A reminder that after each Thursday TRIUMF colloquium (most Thursdays from 2:00 – 3:00pm), GAPS hosts an informal coffee chat with the speaker in the cafeteria from 3:00 – 3:30pm. This is a great way to ask your questions in a more relaxed setting, including questions that expand beyond the scope of the talk such as career-related questions.

The coffee chats continue with this week’s colloquium (see below for more information).

Title: Searching for Time-Reversal Violation Using Pear-Shaped Nuclei in the FRIB Era

Abstract: Experimental tests of fundamental symmetries using nuclei and other particles subject to the strong nuclear force have led to the discovery of parity (P) violation and the discovery of charge-parity (CP) violation. It is believed that additional sources of CP-violation may be needed to explain the apparent scarcity of antimatter in the observable universe. A particularly sensitive and unambiguous signature of time-reversal-(T), parity-, and CP-violation (via the CPT theorem) would be the existence of an electric dipole moment (EDM). The next generation of EDM searches in a variety of complimentary systems (neutrons, atoms, and molecules) will have unprecedented sensitivity to physics beyond the Standard Model. This talk will focus on current and planned experiments that use radioactive isotopes with pear-shaped nuclei. This uncommon nuclear structure significantly amplifies the observable effect of symmetry violations originating within the nuclear medium when compared to isotopes with relatively undeformed nuclei such as Mercury-199. Certain isotopes of Radium (Ra) and Protactinium (Pa) are both expected to have greatly enhanced sensitivity to symmetry violations and will be produced in abundance at the Facility for Rare Isotope Beams currently operating at Michigan State University. I will describe the current status of the ongoing search for the atomic EDM of Ra using laser cooling and trapping techniques as well as the prospects for next generation searches for time-reversal violation possibly using radioactive molecules to further enhance the new physics sensitivity in the FRIB-era. *Some of this work is supported by the U.S. DOE, Office of Science, Office of Nuclear Physics, under contracts DE-AC02-06CH11357, DE-SC0019015, and DE-SC0019455 https://uvic.zoom.us/j/88917215530?pwd=MbYHl3AMr2NzZ2VMNzAtBgoZtHWOro.1 Meeting ID: 889 1721 5530 Password: TRColloq
