论文摘要
在QCD的dyson-schwinger方程的框架内，我们研究有限体积对MIT边界条件的球体手性相变的影响。我们发现，手性夸克冷凝物$ \ langle \barψψ\ rangle $和伪转化温度$ t_ {pc} $随着音量的减小而减小，直到最后没有手性交叉过渡。我们发现，$ r = \ infty $ \ fm的系统与$ r = 10 $ fm无法区分，并且$ t_ {pc} $ a $ r $ as $ r <4 $ fm的$ t_ {pc} $有显着降低。当$ r <1.5 $ fm时，系统中没有手性过渡。
Within the framework of Dyson--Schwinger equations of QCD, we study the effect of finite volume on the chiral phase transition in a sphere with the MIT boundary condition. We find that the chiral quark condensate $\langle\barψ ψ\rangle$ and pseudotransition temperature $T_{pc}$ of the crossover decreases as the volume decreases, until there is no chiral crossover transition at last. We find that the system for $R = \infty $\ fm is indistinguishable from $R=10$ fm and there is a significant decrease in $T_{pc}$ with $R$ as $R<4$ fm. When $R<1.5$ fm, there is no chiral transition in the system.
