A decription of the absolute magnetic field standard for the muon g-2 experiment is now on the arXiv

August 2021

We recently took the chance to reconvene nearly the full group to say goodbye to Christian who moved on to
an new position. All the best, Christian!


July 1, 2021 Dr. Larisa Thorne has joined our group as a postdoc on the Project 8 experiment.
Welcome to Mainz, Larisa!

May 3, 2021 We have been visitied by Ingolf Baur from the 3sat science magazine nano
and his cameraperson Philip Flämig for interviews in the context of our new muon g-2
result. The contribution is accessible in the 3sat mediathek.

April 30, 2021 A small selection of the press coverage this month.

April 7, 2021 A poster summarizing our results (a high resolution version is available here)

April 7, 2021 Today is the day!

The Physical Review Letter describing our result is available here
The description of the analysis of the magnetic field is published in Physical Review A
The description of the analysis of the anomalous precession frequency is published in Physical Review D

You can watch a recording of the seminar here:

The Symmetry Magazin has published another article on Muon g-2.
Fermilab has also produced a great explanatory video.
The result is featured in Physics Viewpoint
In a Physics Special Edition Jorge Cham, aka PhD comics, explains the experiment.

April 2021 Our Muon g-2 collaboration at Fermi National Accelerator Laboratory will present the long-awaited results of its first physics data taking campaign on April 7th, 2021 (17:00 German time). A Nature news article can be found here. An article in the Symmetry Magazine covered the efforts assemble the magnet and to homogenize the magnetic field in the storage ring. The access link to the presentation will be available in time here.

March 2021 The virtual DPG spring meeting is ongoing. Looking forward to the talks presented by our students and postdoc.

March 2021 Congratulations to Christine Claessens for passing her PhD exam with flying colors. Her thesis work on Project 8 addressed the “Event detection in Project 8 - Detection efficiency and its implications for the
first tritium spectrum recorded with Cyclotron Radiation Emission Spectroscopy”. We are really happy to see
that she will continue to work on Project 8 at CENPA, Seattle.

January 2021 Dr. René Reimann was awarded the GNN dissertation award ( for his doctoral thesis titled "Search for the Sources of the Astrophysical High-Energy Muon-Neutrino Flux with the IceCube Neutrino Observatory" (RWTH Aachen, 2019). Congratulations René!

January 2021 Carl-Fabian Strid has joined our group as a graduate student on the tSPECT experiment.
Welcome to Mainz, Carl-Fabian!

October 2020 Hassan Qureshi has joined us as a graduate student to work on the Muon g-2 experiment. Welcome Hassan!

September 2020 The European Commission just approved our Horizon 2020 Research and Innovation Staff Exchanges (RISE) 2020 proposal "aMUSE (advanced Muon Campus in US and Europe contribution)". We are looking forward to travel again to Fermilab in support of the muon g-2 experiment after the Covid-19 situation is under control.

July 2020: Project 8 graduate student, Christine Claessens, is featured in the PRISMA+ news series
"Woran forschen Sie gerade?". Christine is reporting about her stay abroad in Seattle and her participation with the TRIMS experiment that just publsihed its result in Physical Review Letters. Congratulations Christine!

June 2020: A new consensus value for the theoretical expectation of the muon g-2 has been released and can be found here. For more detauils about the involvement of JGU physicist in Muon g-2, please read the press release.

March 2020: We are happy to welcome Dr. René Reimann as a postdoc to our group. René is joining in to our efforts in the muon g-2 and Project 8 experiments.

February 2020: We just finished a great beam time with the τSPECT experiment at the UCN source of the JGU TRIGA reactor facility. Way to go, team!

February 2020: Our Measurement of the Permanent Electric Dipole Moment of the Neutron has been published in Physical Review Letters as an Editor's suggestion and is discussed in Physics, in Physics World and in this JGU press release. And here are some press articles about the result on, and

December 2019: Muon g-2 listed by Nature as one of "The science events to watch for in 2020".

September 2019: My group has officially joined the Muon g-2 experiment at Fermilab.
