论文摘要
从辐射物质到量子染色体动力学的热和密集物质的平稳过渡伴随着有效自由度的连续转变。显微镜描述应包括黑龙内部相互作用的相对论夸克。在这项工作中，我们构建了一个具有相对论运动学的示意图夸克模型，该模型捕获了在光，奇怪和魅力夸克领域中介导的介子光谱的全球趋势。我们研究标量和矢量构成电位的作用，以及半摩托区范围相关性在估计中央，自旋旋转和自旋轨道相互作用的强度中的作用。低洼介子中的夸克动力学对相对论运动学和短距离相互作用非常敏感，而在高层中的介子对标量和矢量填充的组成敏感。在用夸克波函数表达介子之后，我们使用它们来描述介子共振气中的夸克职业概率，并讨论它与夸克 - 格鲁恩 - 帕斯马中的对应物如何相关。
Smooth transitions from hadronic matter to hot and dense matter of quantum chromodynamics accompany continuous transformations in effective degrees of freedom. The microscopic descriptions should include relativistic quarks interacting inside of hadrons. In this work we construct a schematic constituent quark model with relativistic kinematics which captures the global trends of meson spectra in the light, strange, and charm quark sectors. We examine the roles of the scalar- and vector-confining potentials as well as semishort range correlations in estimating the strength of central, spin-spin, and spin-orbit interactions. The quark dynamics in low-lying mesons is very sensitive to relativistic kinematics and short range interactions, while in high-lying mesons are sensitive to the composition of scalar- and vector-confinement. After expressing mesons in terms of quark wave functions, we use them to describe the quark occupation probability in a meson resonance gas, and discuss how it can be related to its counterpart in a quark-gluon-plasma.
