相对论性QED等离子体液滴中的热反应过程

Thermal reaction processes in a relativistic QED plasma drop

Inga Kuznetsova, Dieter Habs, Johann Rafelski

摘要:

在给定的能量含量下,研究了热平衡和化学平衡的$e^+e^-γ$等离子体液滴的平衡尺寸和温度极限。要使等离子体达到平衡,它必须对电子和光子的相互作用不透明。通过比较等离子体尺寸与平均自由电子和光子路径来确定不透明条件。我们计算这些路径使用热洛伦兹不变的反应速率对生产和电子(正电子)和光子散射。相应的等离子体温度和大小的范围进行了数值计算。考虑到能量和尺寸,我们发现不透明和平衡的等离子体液滴是可以实验实现的。

英文摘要:

The equilibrium size and temperature limits of thermally and chemically equilibrated $e^+e^-γ$ plasma drops are investigated at a given energy content. For a plasma to be equilibrated it must be opaque to electron and photon interactions. The opaqueness condition is determined by comparing plasma size with the mean free electron and photon paths. We calculate those paths using thermal Lorentz-invariant reaction rates for pair production and electron(positron) and photon scattering. The range of the corresponding plasma temperature and size is evaluated numerically. Considering the energy and size we find that the opaque and equilibrated plasma drop may be experimentally attainable.
