双夸克涨落和手征软模是如何影响退禁闭相中的双轻子产生的?

How do diquark fluctuations and chiral soft modes affect di-lepton production in the deconfined phase?

Teiji Kunihiro, Masakiyo Kitazawa, Yukio Nemoto

摘要:

在有限温度和密度下,我们分别研究了色超导和手征跃迁的前临界区中存在的双夸克涨落和手征软模。我们评估它们如何有助于反常双轻子产生;虽然由于软模的存在,在谱函数中出现了峰,但产生率的增强可能并不那么突出,而不是相变的明确信号。

英文摘要:

We examine diquark fluctuations and chiral soft modes existing in the precritical region of color superconductivity and chiral transition, respectively, at finite temperature and density. We evaluate how they contribute to anomalous di-lepton production; although there appear peaks in the spectral function owing to the existence of the soft modes, the enhancement of the production rate may not be so prominent to be a clear signal of the phsase transitions.
