摘要:

QCD在高温下会经历一个退澄清的转变,变成一个“夸克-胶子等离子体“的阶段,在那里强子可能会变得不受束缚。本文用最大熵方法研究了束缚相和等离子体相中非零动量的介子关联函数。特别是,纵向和横向模式的矢量关联函数被认为是。只有在等离子体相中的轻夸克的情况下,我们发现,纵向和横向的光谱函数有一个非零的截距在零能量。

英文摘要:

QCD undergoes a deconfining transition at high temperature to a "quark-gluon plasma" phase where hadrons may become unbound. In this work, meson correlation functions at non-zero momentum are studied both in the confined and plasma phases using the Maximum Entropy Method. In particular, both the longitudinal and transverse modes of the vector correlation functions are considered. Only in the case of light quarks in the plasma phase, we find that both longitudinal and transverse spectral functions have a non-zero intercept at zero energy.
