TY - JOUR A1 - Su, Nan T1 - Recent developments in QCD thermodynamics and collective excitations from hard-thermal-loop effective theory T2 - EPJ Web of Conferences N2 - I summarize recent developments in the hard-thermal-loop approach to QCD. I first discuss a finite-temperature and -density calculation of QCD thermodynamics at NNLO from the hard-thermal-loop perturbation theory. I then discuss a generalization of the hard-thermal-loop framework to the magnetic scale g2T, from which a novel non-Abelian massless mode is uncovered.
