奇异夸克物质的量子夸克物质计算

Clustered Quark Matter Calculation for Strange Quark Matter

Xuesen Na

摘要:

由于需要一种固态的奇异夸克物质来更好地解释某些观测现象,我们采用立方标度的夸克质量密度相关模型,按照Clark等(1986)提出的排斥体积方法,通过粗略计算,讨论了冷奇异夸克物质中色单态团簇形成的可能性.发现在10 ~ 50 MeV的温度范围内,1 ~ 10倍核密度下,70%~ 75%的体积和80%~ 90%的重子数处于团簇中。

英文摘要:

Motivated by the need for a solid state strange quark matter to better explain some observational phenomena, we discussed possibility of color singlet cluster formation in cold strange quark matter by a rough calculation following the excluded volume method proposed by Clark et al (1986) and adopted quark mass density dependent model with cubic scaling. It is found that 70% to 75% of volume and 80% to 90% of baryon number is in clusters at temperature from 10MeV to 50MeV and 1 to 10 times nuclear density.
