Under extreme conditions of temperature and/or density, hadronic matter “melts” into a plasma of free quarks and gluons – the so-called quark–gluon plasma (QGP). To create these condit...
Read article 'ALICE tracks charm energy loss in the QGP'
The first direct observation of the suppression of charmed mesons at high transverse-momentum in head-on nucleus–nucleus collisions indicates that charm quarks suffer a strong loss of energy in&...
