最高能量中微子通量的HiRes估计和极限

HiRes Estimates and Limits for Neutrino Fluxes at the Highest Energies

K. Martens

摘要:

高分辨率复眼实验(HiRes)使用空气荧光技术测量最高能量的宇宙射线(CR)。随着犹他州西部达格韦试验场的数据采集工作的完成,HiRes的数据在两个不同的方面与宇宙成因中微子有关。我们首先使用我们最好的拟合测量HiRes CR光谱与模型的河外CR源,以获得预期的宇宙成因中微子和伽马射线通量在地球上。然后,我们直接使用HiRes的数据设置竞争力的实验限制在最高能量的电子和τ中微子通量。

英文摘要:

The High Resolution Fly's Eye Experiment (HiRes) measures cosmic rays (CR) at the highest energies using the air fluorescence technique. As data taking on the Dugway Proving Grounds in Western Utah is finished, the HiRes data are relevant for cosmogenic neutrinos in two different ways. We first use our best fit to the measured HiRes CR spectrum together with a model of the extragalactic CR sources to derive the expected cosmogenic neutrino and gamma ray fluxes at Earth. We then use the HiRes data directly to set competitive experimental limits on the electron and tau neutrino fluxes at the highest energies.
