论文摘要
现代物理学最紧迫的问题之一是暗物质（DM）的本质。已经做出了几项努力来建模这种难以捉摸的问题。 DM的最大比例不能由标准模型的任何已知粒子（SM）制成。我们将重点放在Brane World理论上，作为除粒子物理SM之外的DM候选者的前瞻性框架。在柔性brane世界模型中出现的新的自由度，与勃雷波动相对应，称为麸皮。它们的行为是弱相互作用的巨大颗粒（WIMP），这是DM最喜欢的候选者之一。我们在矮球星系中提供了多目标DM搜索，用于麸皮DM歼灭特征，其基于地面的伽马射线望远镜魔术，导致TEV质量范围内最严格的Branon DM限制。
One of the most pressing questions for modern physics is the nature of dark matter (DM). Several efforts have been made to model this elusive kind of matter. The largest fraction of DM cannot be made of any of the known particles of the Standard Model (SM). We focus on brane world theory as a prospective framework for DM candidates beyond the SM of particle physics. The new degrees of freedom that appear in flexible brane world models, corresponding to brane fluctuations, are called branons. They behave as weakly interacting massive particles (WIMPs), which are one of the most favored candidates for DM. We present a multi-target DM search in dwarf spheroidal galaxies for branon DM annihilation signatures with the ground-based gamma-ray telescope MAGIC leading to the most constraining branon DM limits in the TeV mass range.
