手性不对称物质中双轻子的制备

Dilepton production from chirally asymmetric matter

Nilanjan Chaudhuri, Snigdha Ghosh, Sourav Sarkar, Pradip Roy

摘要:

我们计算了热而致密的手征非对称夸克物质的双轻子产生率。有限的手征化学势(CCP)的存在下,在电磁波谱函数的结果在新的切割结构的出现,标志着额外的散射过程中的介质,这导致显着增强的DPR在较低的不变质量值。使用3味Nambu-Jona-Lasinio模型评估的组分夸克质量也受到CCP的影响。这些被发现导致在一个连续的双轻子生产率作为不变质量的函数的温度和重子化学势较高的值。

英文摘要:

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.
