论文摘要
我通过一种称为“典型轴心”的非常轻的伪库来回顾深色能源解决方案。对于明确的破坏术语，我们同时考虑全局异常u（1）$ _ {\ rm global} \ times $ su（2）$ _ w^2 $和潜在的$ΔV$。在现场理论层面上，我们将提出一项策略，以在大量伪级中拾取这样的伪库。在弦级上，许多反对称张量场是伪尺度。包括这些，我们通过$ z_ {12-i} $ orbifold cartactification so（32）异源字符串提出一个限制力量示例。此外，我们还旨在引起人们对几乎无质量的隔离非阿布尔仪表群的关注，这可能是引入额外的限制力的另一个动机，以解释黑暗能量作为这些介子的真空能量。
I review the dark energy solutions by a very light pseudoscalar called "quintessential axion". For the explicit breaking terms, we consider both the global anomaly U(1)$_{\rm global}\times$SU(2)$_W^2$ and the potential $ΔV$. At the field theory level, we will present a strategy for picking up one such pseudoscalar among plenty of pseudoscalars. At string level, numerous antisymmetric tensor fields are pseudoscalars. Including these, we present a confining force example via a $Z_{12-I}$ orbifold compactification of SO(32) heterotic string. In addition, we also aim to draw attention on almost massless mesons of confining nonabelian gauge group, which can be another motivation for introducing an additional confining force, to explain dark energy as the vacuum energy of these mesons.
