ALICE explores the hidden charm of quark–gluon plasma（图）
ALICE 夸克-胶子 等离子体
font style='font-size:12px;'>
2023/5/26
Quark–gluon plasma is an extremely hot and dense state of matter in which the elementary constituents – quarks and gluons – are not confined inside composite particles called hadrons, as they are in t...
Mass matters when quarks cross a quark–gluon plasma（图）
