论文摘要
我们评估了热和密集的手性不对称夸克物质的DILEPTON生产率（DPR）。电磁光谱功能中存在有限的手性化学电位（CCP）导致新切割结构的出现，表示介质中的其他散射过程，从而导致DPR在较低的不变质量值下的显着增强。使用3流动NAMBU-JONA-LASINIO模型评估的组成夸克质量也受到CCP的无误影响。发现这些导致连续的DILEPTON生产速率与较高的温度和重型化学势值相比，这是不变质量的函数。
We evaluate the dilepton production rate (DPR) from hot and dense chirally asymmetric quark matter. The presence of a finite chiral chemical potential (CCP) in the electromagnetic spectral function results in the appearance of new cut structures signifying additional scattering processes in the medium which leads to a significant enhancement in the DPR at lower values of invariant mass. The constituent quark mass evaluated using a 3-flavour Nambu--Jona-Lasinio model is also non-trivially affected by the CCP. These are found to result in a continuous dilepton production rate as a function of the invariant mass for higher values of temperature and baryonic chemical potential.
