摘要

根据局部SU(3) Nambu-Jona-Lasinio (NJL)模型，研究了中微子振荡对三味热夸克物质在β-平衡中的热力学特性的影响，该模型也解释了导致夸克味混合的' t Hooft相互作用。在考虑中微子振荡的情况下，确定了夸克物质在T = 60和100 MeV两种温度下的热力学特性。这些结果与不考虑中微子振荡的结果进行了比较。计算表明，在对中微子不透明的夸克物质冷却过程中，每单位重子电荷释放的能量为150 ÷ 350 MeV。

Effect of Neutrino Oscillations on the Thermodynamic Properties of Hot Quark Matter

The effect of neutrino oscillations on the thermodynamic characteristics of three-flavor hot quark matter in β-equilibrium that is opaque for neutrinos is examined in terms of the local SU(3) Nambu-Jona-Lasinio (NJL) model which also accounts for the ‘t Hooft interaction that leads to quark flavor mixing. The thermodynamic characteristics of quark matter are determined for two temperatures, T = 60 and 100 MeV, with neutrino oscillations taken into account. These results are compared with those obtained without taking neutrino oscillations into account. The calculations show that during cooling of quark matter that is opaque to neutrinos, the energy released per unit of baryon charge is 150 ÷ 350 MeV.
