论文摘要
我们考虑夸克 - 格鲁恩等离子体中的介子和巴里昂的产生，用于对撞机的早期宇宙和超层次的重离子碰撞。我们调查的基本特征是考虑到Meson和Baryon生产下的夸克的潜在障碍。我们已经使用玻尔兹曼方程来描述夸克融合的动力学过程。我们为动力学方程解提供了分析表达式。这允许找到反应速率对时间，温度，质量和夸克的电荷以及与狭窄电势相关的弦张力的依赖性。接下来，我们详细考虑了在超偏移重离子碰撞中的某些具体动力学过程中的介子和重子产生。对于扩展宇宙的过程，完全相同的结果将是正确的
We consider the meson and baryon production in the quark-gluon plasma as applied to the early Universe and ultrarelativistic heavy ion collisions in collider. The essential feature of our investigation is to take into account a potential barrier for quarks under meson and baryon production. We have used the Boltzmann equation to describe kinetic processes of quark fusion. We have derived analytic expressions for solutions of kinetic equations. This permits to find the dependence of reaction rate on a time, temperature, mass and charge of quarks as well as on a string tension connected with the confining potential. Next we have considered in detail the meson and baryon production for some concrete kinetic processes in collisions of ultrarelativistic heavy ions. Exactly the same results will be as well true for processes in expanding Universe
