NIC Excellence Project April 2021

The NIC Peer Review Board regularly awards the title "NIC Excellence Project" to outstanding simulation projects. At its April meeting, the board decided to honour Prof. Szabolcs Borsanyi (University of Wuppertal) for his work on the determination of the strong interaction from the Standard Model of particle physics and his special focus on the determination of the magnetic moment of the muon.

The Standard Model of particle physics describes all known elementary particles and their interaction. For example, the existence of the Higgs boson was successfully predicted with this model – an achievement that was honoured with the Nobel Prize in Physics in 2013. However, discrepancies between theory and experiment continue to arise, for example in the determination of the magnetic moment of the muon. The work of Prof. Borsanyi et al. (DOI: 10.1038/s41586-021-03418-1) was able to resolve this discrepancy by calculating the interaction of the particles involved with the exclusive help of the Standard Model and without the use of experimental data. A large fraction of the computations was carried out on the supercomputers at FZJ.

Furthermore, the NIC acknowledges the work on the calculation of heavy ion experiments using the Standard Model. Here, extreme physical conditions have to be taken into account as well as the high demands placed on the theory and the experiment.
