论文摘要
在冰中中微子相互作用后，无线电发射的检测是一种有前途的技术，是获得对PEV高能量的中微子的显着敏感性。可检测到的无线电发射来自冰中的粒子阵雨。到目前为止，检测器模拟仅考虑了中微子主要相互作用的无线电发射。在这项研究中，现有的仿真工具已扩展以涵盖Muons和Taus的次要相互作用。我们发现，两个卵子的次级相互作用均高达25 \％，其中有效中微子探测器的有效体积。同样，Muon和Tau Neutminos可以产生几个可检测的阵雨，结果双签名并不构成Tau Neutminos的独家签名。我们还发现，来自宇宙射线的大气压背景对于冰上阵列不可忽略，并且应将空气淋浴否决视为对无线电探测器有帮助。
The detection of the radio emission following a neutrino interaction in ice is a promising technique to obtain significant sensitivities to neutrinos with energies above PeV. The detectable radio emission stems from particle showers in the ice. So far, detector simulations have considered only the radio emission from the primary interaction of the neutrino. For this study, existing simulation tools have been extended to cover secondary interactions from muons and taus. We find that secondary interactions of both leptons add up to 25\% to the effective volume of neutrino detectors. Also, muon and tau neutrinos can create several detectable showers, with the result that double signatures do not constitute an exclusive signature for tau neutrinos. We also find that the background of atmospheric muons from cosmic rays is non-negligible for in-ice arrays and that an air shower veto should be considered helpful for radio detectors.
