4维Lorentz复结构依赖的YM类模型的微扰禁闭

Perturbative Confinement in a 4-d Lorentzian Complex Structure Dependent YM-like Model

C. N. Ragiadakos

摘要:

我继续研究一个可重整化的四维一般协变的杨-米尔斯类作用量,它依赖于时空的洛伦兹复结构,而不是它的度规。场方程及其可积性条件被明确地写下来。该模型研究了平凡圆柱复杂结构中存在两个静态外源的情况。两个静态的“有色”源的能量被发现线性增加相对于他们的距离,提供了一个明确的证明他们的微扰禁闭。在本模型中,禁闭不是规范群的非阿贝尔性质的必然结果,而是由模型的复杂结构依赖性所隐含的。

英文摘要:

I continue the study of a renormalizable four-dimensional generally covariant Yang-Mills-like action, which depends on the Lorentzian complex structure of spacetime and not its metric. The field equations and their integrability conditions are written down explicitly. The model is studied with the presence of two static external sources in the trivial cylindrical complex structure. The energy of two static "colored" sources is found to increase linearly with respect to their distance, providing an explicit proof of their perturbative confinement. In the present model, confinement is not a concequence of the non-Abelian character of the gauge group, but it is implied by the complex structure dependence of the model.
