quark confinement 解釋
夸克禁閉
  • quark : n. 夸克〈假設的帶電核粒子，為已知的粒子如質子及中子等的基本構成部分〉。
  • confinement : n. 1. 限制，界限，拘束；（電磁）吸持。2. 幽禁，監禁；拘留；【物理學】密封，密閉。3. 閉居，退隱。4. 產期，分娩期。
  1. In quantum chromodynamics ( qcd ), vacuum is not trivial, that is, vacuum carry quantum numbers. such a behavior is embodied by non - perturbative con - densates of quarks and gluons. since hadrons are excitations with respect to the vacuum, hadronic properties are ultimately related to properties of the vacuum. based on the vacuum structure, some hadron properties have been described well. in the low energy region, qcd has two very important proper - ties : chiral symmetry spontaneous breaking and confinement, which are closely related to the vacuum characteristics of qcd. much experiments and theoretical studies have shown that chiral symmetry spontaneous breaking is very important to understand the low - energy feature of the strongly interacting physics, and the quark condensates give an expression to chiral symmetry spontaneous breaking. according to goldstone ' s theorem, the goldstone bosons with zero mass will emerge as the chiral symmetry is spontaneously broken. there are two ways : inear and non - linear methods to carry out this constraint. in our paper, we will use the non - linear method

    大量實驗和理論研究表明，手征對稱自發破缺對于理解低能強相互作用十分重要，而夸克凝聚又是導致手征對稱自發破缺的因素。按goldstone理論，伴隨手征對稱自發破缺應該會有零質量的goldstonebosons產生。而對于這一條件的實現有線性和非線性兩種方法本文將用非線性的方法將手征對稱自發破缺應用於su （ 3 ）模型即重子八重態，得出描述其強相互作用的手征對稱自發破缺lagrange密度。
  2. Second, we obtain a new quark potential from the effective dilaton - gluon - coupling inspired by superstring theory and devote more effects to understand this new confinement generating mechanism through the investigation of the phenomenological application of this interquark potential in the heavy mesons sector

    其次，由超弦理論啟發的伸縮子?膠子有效耦合，給出了一種新的夸克勢，並在重介子系統中研究了這個勢提供的禁閉機制。
  3. We obtain a new quark potential from the effective dilaton - gluon - coupling inspired by superstring theory, and by using this static potential, we explore the mechanism of quark confinement through calculations of the spin - average energy levels, the widths of the leptonic decays and radiative transitions for heavy quarkonium. the obtained results are compared with that of the cornell potenial

    由規范場理論的超弦理論所激發的伸縮子一膠子有效藕合，給出了一個新的靜態夸克一反夸克勢，討論了此勢模型下重介子的自旋平均能譜、輕子衰變和輻射躍遷寬度，並與cdrn叭勢模型所得到的相應結果作了比較
  4. Analogy and duality between charge - confinement and quark - confinement

    電荷禁閉和夸克禁閉的相似性與對偶性
  5. Second, the quark potential has to be at present determined phe - nomenologically due to qcd nonperturbation and the mechanism of quark confinement is still in search

    尹其次，由於夸克勢只能唯象地得到，夸克禁閉機制及其對重介子的影響仍在探索之中
