论文摘要
我们计算在循环重新召集理论框架中的热磁和磁化QCD物质中计算颜色筛选质量，而无需限制磁场强度。我们的完整计算涵盖了在高温下经常使用的弱磁场和强磁场的近似值。我们发现，尽管在RHIC和LHC能量的重离子碰撞中产生的磁场可能是最强的，但与火球的高温相比，其对QCD物质的影响仍然较弱，因此可以安全地将其视为扰动。
We calculate color screening mass in a thermalized and magnetized QCD matter in the frame of loop resummation theory without restriction to the magnetic field strength. Our full calculation covers the often used approximations for weak magnetic field at high temperature and strong magnetic field at low temperature. We find that while the magnetic field created in heavy ion collisions at RHIC and LHC energies is probably the strongest one in nature, its effect on the QCD matter is still weaker in comparison with the high temperature of the fireball, and therefore can safely be treated as a perturbation.
