Hadronic matter under extreme conditions

" The development of observations and laboratory experiments make itpossible to explore the extreme conditions such as very high temperature,





high density, strong magnetic field and strong gravity, under which newphysics of matters are expected or can be tested. It is believed that astrongly interacting hadrons must melt down in the form of quark andgluons above certain temperature, which has been confirmed in relativisticheavy ion collision experiments as well as from the cosmologicalconsideration of early universe."
