唯象QCD模型中的色对称超导电性

Color symmetric superconductivity in a phenomenological QCD model

Henrik Bohr, Constança Providência, João da Providência

摘要:

在本文中,我们构建了一个NJL型的理论,其中超导性是存在的,但超导状态仍然是,在平均,颜色对称。这表明,目前的颜色超导性的方法是一致的颜色单态。事实上,夸克在退禁闭相中是自由的,但退禁闭相本身被认为是一种色单线态。通常对色超导态的描述违反了色单态性。另一方面,这里提出的色超导态是色对称的,在这个意义上,任意的颜色旋转导致一个等价的状态,具有完全相同的物理性质。

英文摘要:

In this paper, we construct a theory of the NJL-type where superconductivity is present, and yet the super-conducting state remains, in the average, color symmetric. This shows that the present approach to color superconductivity is consistent with color singlet-ness. Indeed, quarks are free in the deconfined phase, but the deconfined phase itself is believed to be a color singlet. The usual description of the color superconducting state violates color singlet-ness. On the other hand, the color superconducting state here proposed, is color symmetric in the sense that an arbitrary color rotation leads to an equivalent state, with precisely the same physical properties.
