改进的夸克质量密度依赖模型的夸克退禁闭相变

Quark deconfinement phase transition for improved quark mass density-dependent model

Chen Wu, Ru-Keng Su

摘要:

利用有限温度量子场论,计算了有限温度下的有效势,并将改进的夸克质量密度依赖模型推广到有限温度下。结果表明,该模型不仅能描述核物质的饱和性质,而且能成功地解释夸克退禁闭相变。给出了临界温度,并讨论了$ω$介子的影响.

英文摘要:

By using the finite temperature quantum field theory, we calculate the finite temperature effective potential and extend the improved quark mass density-dependent model to finite temperature. It is shown that this model can not only describe the saturation properties of nuclear matter, but also explain the quark deconfinement phase transition successfully. The critical temperature is given and the effect of $ω$- meson is addressed.
