摘要
从核完全阻止的假定出发,基于一个相对论性流体力学模型,研究了富重子夸克-胶子物质的双轻子产生,发现随着入射能量的增加,在双轻子总产额中出现一个标志富重子夸克-胶子物质形成的特征平台,这样显著的特征可在CEEN和Brookhaven即将开展的实验中得到检验。
From the full stopping scenuio, the dilepton producdon in the baryon-rich quarktgluon fircball is studicd based on a reladvisdc hydrodynamic model. It is found that with increasing incident cnergy a characteristic plateau indicadng the formation of the baryon-rich quarktgluon matter appears in the total yield. This obvious characteristic can be tested in future experiments at CERN and Brookhaven.
