A team of physicists from the University of Wuppertal are using the JUWELS and JURECA supercomputers at the Jülich Supercomputing Centre (JSC) to better understand the Brout-Englert-Higgs mechanism, which explains how elementary particles acquire mass. The team developed an algorithm that helps them measure the so-called Higgs potential, which allows the researchers to better understand the behavior of elementary particles. This allows the team to investigate gauge-Higgs unification models that propose a unification of the electromagnetic and weak forces—two of the fundamental forces of nature.

Using JSC resources, the team performed very precise “constrained” simulations where the Higgs field fluctuates around a fixed expectation value only, that allow the team to explore regions of the phase space throughout their simulation which cannot be reached by histogram methods. The team published the results in Computer Physics Communications.
