论文摘要
拟议的DarkQuest Beam Dump实验是对现有的Seaquest/SpinQuest实验的适度升级，具有在黑暗扇区内发现新物理的巨大潜力。我们探索了观察两个不同的，高度动机的隐藏扇形基准模型的近期和长期前景：重型中性瘦素和希格斯混合标量。我们全面检查了Darkquest的颗粒产生和检测器的接受度，包括对介子产生的更新处理，以及通过Bremsstrahlung和Gluon-Gluon融合的轻量积生产。在这两个基准模型中，DarkQuest将在相当短的时间表上与其他提出的实验相比，在相当短的时间范围内探测以前无法访问的参数空间的有趣区域。
The proposed DarkQuest beam dump experiment, a modest upgrade to the existing SeaQuest/SpinQuest experiment, has great potential for uncovering new physics within a dark sector. We explore both the near-term and long-term prospects for observing two distinct, highly-motivated hidden sector benchmark models: heavy neutral leptons and Higgs-mixed scalars. We comprehensively examine the particle production and detector acceptance at DarkQuest, including an updated treatment of meson production, and light scalar production through both bremsstrahlung and gluon-gluon fusion. In both benchmark models, DarkQuest will provide an opportunity to probe previously inaccessible interesting regions of parameter space on a fairly short timescale when compared to other proposed experiments.
