论文摘要
当前的实验对非常弱耦合的额外量规对称性很敏感，这激发了其在弦理论压缩和随后的特性中的外观进一步研究。我们考虑基于d-branes上末尾的开放字符串的标准模型的扩展，由于串附着在堆叠的d-branes和手性质的情况下，仪表玻色子是由于伸展的串线在相交的d-branes之间伸展而引起的。假设基本的弦质量量表使当前的LHC极限饱和，并且该理论是弱耦合的，我们表明（异常的）$ u（1）$量规玻色子，将大量传播到散装中是引人注目的轻型暗物质候选者。我们对$ U（1）$量规玻色子的可能相关性发表评论，该玻色子在与Xenon1t中观察到的$3σ$多余的$3σ$多余的相交中通用。
Present experiments are sensitive to very weakly coupled extra gauge symmetries which motivates further investigation of their appearance in string theory compactifications and subsequent properties. We consider extensions of the standard model based on open strings ending on D-branes, with gauge bosons due to strings attached to stacks of D-branes and chiral matter due to strings stretching between intersecting D-branes. Assuming that the fundamental string mass scale saturates the current LHC limit and that the theory is weakly coupled, we show that (anomalous) $U(1)$ gauge bosons which propagate into the bulk are compelling light dark matter candidates. We comment on the possible relevance of the $U(1)$ gauge bosons, which are universal in intersecting D-brane models, to the observed $3σ$ excess in XENON1T.
