The exotic frontiers of nuclear physics

The non-perturbative nature of quantum chromodynamics (QCD) has historically left a gap in our understanding of the connection between the fundamental theory of the strong interactions and the rich structure of experimentally observed phenomena. For the simplest properties of stable hadrons, this is now circumvented by utilizing lattice QCD (LQCD). In this talk I discuss a path that will allow us to access a variety of previously unexplored sectors of QCD. As a proof of principle, I will focus my attention to the isoscalar-scalar sector of QCD. Carrying the quantum numbers of the vacuum, this is perhaps one the most interesting channels of nuclear physics. Beyond playing a crucial role in a range of phenomenologically important processes, it hosts some some of the most intriguing states of QCD. For example, glueballs, which have long been upheld as a smoking gun of the low-energy validity of QCD, are expected to appear in this channel. I restrict my attention to low energies and discuss the manifestation of the lightest of all hadronic resonances, the sigma/f0(500), in QCD.
