The interaction between partons – quarks and gluons – within quark-gluon plasma is strong, which distinguishes the quark-gluon plasma from a gaseous state where one expects little interaction among the constituent particles,” said team member Dr Quan Wang of the University of Kansas. “Before the CMS experimental results, it had been thought the medium created in a proton on lead collisions would be too small to create quark-gluon plasma.”
