论文摘要
下一代射电望远镜将通过测量超高能量中微子对低尺度量子重力敏感。在这封信中，我们首次证明了由TEV尺度重力引起的中微子核子软相互作用将显着增加EEV制度中Icecube-gen2无线电阵列检测到的事件数量。但是，我们表明这些实验不能仅使用中微子通量的角和能量信息来测量总横截面，除非对中性相互作用的潜在非弹性分布进行假设。
The next generation of radio telescopes will be sensitive to low-scale quantum gravity by measuring ultra-high-energy neutrinos. In this letter, we demonstrate for the first time that neutrino-nucleon soft interactions induced by TeV-scale gravity would significantly increase the number of events detected by the IceCube-Gen2 radio array in the EeV regime. However, we show that these experiments cannot measure the total cross section using only the angular and energy information of the neutrino flux, unless assumptions on the underlying inelasticity distribution of neutral interactions are made.
