ISOLDE PGM

Tuesday 31 May 2022, 16:00 → 18:00 Europe/Zurich

4/3-006 - TH Conference Room (CERN)

News of the week will be followed by a short report on the Ac run over the weekend. 

We will then have a seminar given by Prof. Jacinda Ginges, with the title"On the Bohr-Weisskopf effect and atomic parity violation"

The abstract can be found here: 

 

In this talk I will discuss the Bohr-Weisskopf (BW) effect, and its relevance to tests of the standard model and searches for new physics in atomic parity violation studies. The BW effect gives the finite nuclear magnetisation contribution to the hyperfine structure, and is difficult to quantify at the required level of accuracy from nuclear structure theory. I will describe how — through a combination of atomic theory and atomic and nuclear experiments — the BW effect may be determined. An accurate understanding of the BW effect is needed for reliable tests of atomic structure theory in the nuclear region, and for the development of precision atomic many-body methods. This is important for the error analysis of atomic parity violation studies, and for maximising the impact on particle physics discovery.
