The article of researchers at MTA Wigner RCP in collaboration with ELTE and University of Debrecen is a leading news at The European Physical Journal (EPJ) : https://www.epj.org/epja-news/1292-epja-highlight-nuclear-and-quark-mat…. In the article the researchers are saying that  hadrons are melting like the butter in the sun: " In high-temperature field theory applied to nuclear physics, in particular to relativistic heavy-ion collisions, it is a longstanding question how hadrons precisely transform into a quark-gluon matter and back. The change in the effective number of degrees of freedom is rather gradual than sudden, despite the identification of a single deconfinement temperature. "
