Emergent hadrons and diquarks

We discuss the emergence of a low-energy effective theory with quarks, mesons, diquarks and baryons at vanishing finite baryon density from first principle QCD. The present work also includes an overview on density, elucidates physics transitional changes baryonic matter to quark including diquarks. This set-up is discussed within functional renormalisation group approach dynamical hadronisation. In this framework it detailed how diquarks, emerge dynamically flow QCD action. Moreover, fundamental degrees freedom QCD, quarks gluons, decouple dynamics below respective mass gaps. resulting global picture unifies different low energy theories used for high densities allows determination constants directly
