Time: 10:00 am, Sep 14th (Thursday), 2023Location: 理科楼C302Title: Experimental test of quark deconfinement — hadrons with charm quarksSpeaker: Johanna Stachel (Heidelberg University)Abstract: The production of hadrons in relativistic nuclear collisions with up to three charm quarks is strongly enhanced if the quarks in the hot fireball are deconfined. We will describe how this comes about in...
