通过求解膨胀夸克-胶子等离子体(QGP)中的速率方程,我们研究了未来圆形对撞机中心铅+铅碰撞中魅力夸克的热产生。从微扰QCD得到的魅力夸克产生截面位于次前级,我们发现QGP产生的魅力夸克与碰撞核子初始硬散射产生的魅力夸克相比是可以观察到的。
By solving the rate equation in an expanding quark–gluon plasma (QGP), we study thermal production of charm quarks in central Pb + Pb collisions at the Future Circular Collider. With the charm quark production cross section taken from the perturbative QCD at the next-to-leading order, we find that charm quark production from the QGP can be appreciable compared to that due to initial hard scattering between colliding nucleons.
