The XVIII International Conference on Strangeness in Quark Matter (SQM 2019) This book focuses on new experimental and theoretical advances concerning the role of strange and heavy flavour quarks in high energy heavy ion collisions and in astrophysical phenomena. The topics covered include • Strangeness and heavy quark production in nuclear collisions and hadronic interactions • Hadron resonances in the strongly coupled partonic and hadronic medium • Bulk matter phenomena associated with strange and heavy quarks • QCD phase structure • Collectivity in small systems • Strangeness in astrophysics • Open questions and new developments. .
