Even though QCD is the underlying theory of nuclear interactions, its direct connection with various nuclear phenomena remains unclear. The fundamental questions about the role of the quark-gluon dynamics, confinement and the generation of mass remain qualitative at best. The vast majority of hadrons are unstable and in experimental measurements appear indirectly via complicated distributions of decay products. This poses substantial challenges in interpreting the experimental data and analyzing the spectrum of QCD experimentally as well as theoretically. In recent years new high-quality data from experimental facilities, together with rapid developments in ab-initio theoretical applications, have enabled us to address the most formidable questions regarding the formation of QCD bound states.
