We map out the QCD phase structure at finite temperature and chemical potential for 2-flavour 2 + 1-flavour QCD. This is done within a generalised functional approach to put forward in arXiv:2002.07500 [hep-ph]. Specifically we compute quark propagator finite-temperature density fluctuations of gluon quark-gluon vertex on basis precision data vacuum correlation functions. The novel ingredient d...
