我们研究了 LPM 效应对冰相干无线电波区域中 EeV 电磁簇射切伦科夫辐射的影响。我们表明，对于高于 100 PeV 的流星雨，电场与流星雨能量成比例，但与较低能量的流星雨相比，其角度分布明显更窄。我们给出了对于能量高达 EeV 范围的簇射有效的电场频率和角谱参数化，并讨论了对基于无线电天线阵列的中微子探测器的影响。还简要讨论了 LPM 效应对项目中水下中微子探测器的影响。
We study the implications of the LPM effect for the Cherenkov radiation of EeV electromagnetic showers in the coherent radiowave regime for ice. We show that for showers above 100 PeV the electric field scales with shower energy but has a markedly narrower angular distribution than for lower energy showers. We give an electric field frequency and angular spectrum parameterization valid for showers having energy up to the EeV regime and discuss the implications for neutrino detectors based on arrays of radio antennas. Implications of the LPM effect for under water neutrino detectors in project are also briefly addressed.
