论文摘要
质子束降低实验是次级元音的高强度来源，并为探测MUON特异性的黑暗扇区提供了机会。我们采用一个简化的模型框架，主要或仅与Muons建立异国情调的标量粒子耦合。配备了最先进的MUON模拟，我们计算了黑暗中介器的参数空间$（M_S，\，G_μ）$中的灵敏度达到，并详细检查了Beam-Dump模式的实验Na62的示例和拟议的实验船。我们发现此类外来物质在亚GEV质量范围内的显着产率。我们的预测与主要的MUON梁实验的竞争性和与当前约束的补充，跨越了未知的参数空间，并访问了可能负责$（G-2）_μ$异常的新物理学。
Proton beam-dump experiments are a high-intensity source of secondary muons and provide an opportunity to probe muon-specific dark sectors. We adopt a simplified-models framework for an exotic light scalar particle coupling predominantly or exclusively to muons. Equipped with state-of-the-art muon simulations, we compute the sensitivity reach in the parameter space $(m_S, \, g_μ)$ of the dark mediator, examining in detail the examples of the experiment NA62 in beam-dump mode and the proposed experiment SHiP. We find a significant yield of such exotics in the sub-GeV mass range. Our projections are competitive with those of primary muon-beam experiments and complementary to current constraints, spanning uncharted parameter space and accessing new physics potentially responsible for the $(g-2)_μ$ anomaly.
