摘要
为了更好地从双轻子信息研究夸克-胶子等离子体,本文利用正反夸克湮灭产生双轻子的反应截面,考虑到夸克-胶子等离子体的动量分布满足玻尔兹曼分布,在假设夸克和轻子的质量为0的情况下,推出了等离子体中双轻子的产率.结果表明双轻子的产率与等离子体温度的4次方成正比.
For better researches on Quark-gluon Plasma through the dilepton,we derive the dilepton production rate in the Quark-gluon Plasma from the annihilation cross-section of the quark-antiquark.Moreover,the Quark-gluon Plasma whose momentum distribution satisfies Boltzmann distribution is considered,and the quality of quarks and leptons is neglected.The result shows that the dilepton production rate is proportional to the biquadratic of the plasma's temperature.
