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.

拟议的DarkQuest光束倾卸实验是对现有SeaQuest / SpinQuest实验的适度升级，具有发现暗区中新物理的巨大潜力。我们将探索观察两种截然不同的，充满动力的隐性部门基准模型的近期和长期前景：重型中性轻子和希格斯混合标量。我们在DarkQuest上全面检查​​了粒子的产生和检测器的接受程度，包括对子产生和胶子-胶子聚变的介子产生和光标量产生的更新处理。在两个基准模型中，与其他拟议的实验相比，DarkQuest将提供一个机会，可以在相当短的时间内探测以前无法访问的参数空间的有趣区域。
