Quark scattering off quarks and hadrons

A. V Friesen, Yu. V. Kalinovsky, V. D. Toneev

摘要:

在双味Polyakov环扩展的Nambu-Jona-Lasinio模型下计算了介质中弹性散射$qq\to qq, q\bar{q}\to q\bar{q}$和$\bar{q}\bar{q}\to \bar{q}\bar{q}$。考虑了夸克-夸克的积分散射和微分散射及其能量和温度依赖性,并强调了它们的味依赖性。与其他方法的结果进行了比较。在动力学多相处理中考虑了表征夸克与强子相互作用的夸克-π散射,给出了夸克-π截面的初步估计.一个可能的应用所获得的结果的重离子碰撞进行了讨论。

英文摘要:

The in-medium elastic scattering $qq\to qq, q\bar{q}\to q\bar{q}$ and $\bar{q}\bar{q}\to \bar{q}\bar{q}$ is calculated within the two-flavor Polyakov-loop-extended Nambu-Jona-Lasinio model. The integral and differential quark-quark scattering, its energy and temperature dependence are considered and their flavor dependence is emphasized. The comparison with results of other approaches is presented. The consideration is implemented to the case of quark-pion scattering characterizing the interaction between quarks and hadrons in a kinetic multiphase treatment, and the first estimate of the quark-pion cross sections is given. A possible application of the obtained results to heavy ion collisions is shortly discussed.
