Abstract given by the source: This computing project aims to understand the mechanism that binds quarks and gluons to hadrons and multiquark systems. Atomic nuclei are bound states of nucleons, the proton and neutron, but simultaneously bound states of confined quarks and gluons, which are the fundamental degrees of freedom of Quantum Chromodynamics (QCD), the theory of the strong interaction. Experimental evidence suggests that nature does not only form “conventional” hadrons, such as mesons as quark-antiquark states and baryons as three-quark states, but also exotic ones like tetraquarks, pentaquarks and hexaquarks. This suggests an intrinsic connection between the structure of multiquarks and light nuclei, which is not yet understood: Do quarks and gluons form hadronic clusters inside multiquarks, like protons and neutrons in atomic nuclei? How do short-range nuclear correlations emerge microscopically? What happens when the clusters are so close that they begin to overlap? What is the role of gluons in the dynamical generation of a hadron’s mass? Which exotic hadrons exist, and how can we find them experimentally? To answer these questions, we employ functional methods to calculate the spectrum of multiquarks from first principles. We solve the self-consistent Dyson-Schwinger equations for QCD's elementary quark and gluon correlation functions, which enter in the multiquark calculations. We apply for 1.024.000 CPU hours over 12 months.
