AI总结:

本文研究射电中微子探测器中高能大气缪子能量损失产生的背景,评估其速率不确定性,并探讨通过母空气簇射探测等途径减轻背景,以实现 10 PeV 以上瞬发缪子通量的首次测量。

摘要:

旨在探测中微子相互作用产生的射电辐射的实验即将达到能够实现探测的灵敏度。由于像 RNO-G 或未来的 IceCube-Gen2 这样的实验目标有效体积比现有实验大一个数量级以上,因此需要对稀有背景进行重新详细研究。在本文中,我们研究了高能大气缪子能量损失产生的潜在背景。由于实验测量有限以及强子相互作用模型中的建模有限,预期事件率存在很大的不确定性。在这里,我们估算了不同模型和仪器参数下的速率预测及其不确定性。我们还研究了减轻缪子背景的可能途径,例如母空气簇射探测,并说明了在 10 PeV 以上能量进行首次瞬发缪子通量测量所需的条件。

英文摘要:

Experiments seeking to detect radio emission stemming from neutrino interactions will soon reach sensitivities that bring a detection within reach. Since experiments like RNO-G or the future IceCube-Gen2 target more than an order of magnitude more effective volume than existing experiments, the renewed and detailed study of rare backgrounds is needed. In this paper, we study the potential background from energy losses of highly energetic atmospheric muons. Due to both limited experimental measurements and limited modeling in hadronic interaction models, the expected event rate is subject to large uncertainties. Here, we estimate rate predictions and their uncertainties for different models and instrumental parameters. We also study possible routes towards mitigation of the muon background, such as parent air shower detection, and illustrate what is needed to make the first measurement of the prompt muon flux at energies above 10 PeV.
