Applications from Elementary Particle Physics
Here we present a choice of impressive projects from elementary particle physics which have been carried out on GCS supercomputers.
Heavy Ion Phenomenology Form Lattice Simulations
A team of physicists used JSC supercomputer JUQUEEN to study the energy density, entropy, specific heat and pressure of quark gluon plasma, starting from a high temperature at its creation to a low temperature where the plasma actually freezes. Their goal: to identify the plasma's break-up point, i. e. the point when the plasma freezes and its matter is transformed into subatomic particles.

2+1+1 Lattice QCD Calculations With HEX Smeared Clover Fermions
Supercomputer resources of GCS enable physicists to solve the equations of QCD on a large enough and simultaneously fine enough lattice to accurately compute the effects of the charm quark and predict the masses of short-lived particles it is contained in.

Fluctuations of Conserved Charges in the Quark Gluon Plasma
Leveraging the vast computing power of HPC system JUQUEEN of JSC, an international team of physicists aims on a model independent determination of the freeze-out temperature and density of Quark Gluon Plasma (QGP), based on the fundamental equations of the theory of strongly interacting matter, Quantum Chromodynamics (QCD).

The dominance of matter over antimatter in our universe is one of the unsolved riddles of present day physics. During the early phases of our universe, matter must have been produced predominantly over antimatter, but the only such process we currently know only affects quarks, the fundamental constituents of the atomic nucleus, and does not provide enough matter dominance.
