中微子物理学的高能范围（高于$\sim 10^{7} \，\mathrm{GeV}$），迄今为止还没有探测到，是一个开放的景观，需要迎接挑战和发现。在这个范围内的中微子-核子截面-动量中心能量为$\sqrt{s} \gtrsim 4 \，\mathrm{TeV}$ -是对未知现象的有力探测。我们提出了一个简单而准确的模型无关的框架，以评估如何以及这些横截面可以测量一个未知的通量和通用探测器。我们还演示了如何表征和比较检测器的灵敏度。我们表明，截面可以测量到$\simeq ^{+65}_{-30}$%的精度超过$\sqrt{s} \simeq $4 -140 TeV（$E_\nu = 10^7$-$10^{10}$ GeV）与适度的能量和角分辨率和$\simeq 10$事件每能量十年。许多人允许新的物理模型（额外的维度，leptoquark等）。产生更大的影响。在遥远的未来，在最高能量下发生$\simeq 100$事件，精度将达到$\simeq 15\%$，甚至可以探测QCD饱和效应。
The ultrahigh energy range of neutrino physics (above $\sim 10^{7} \, \mathrm{GeV}$), as yet devoid of detections, is an open landscape with challenges to be met and discoveries to be made. Neutrino-nucleon cross sections in that range - with center-of-momentum energies $\sqrt{s} \gtrsim 4 \, \mathrm{TeV}$ - are powerful probes of unexplored phenomena. We present a simple and accurate model-independent framework to evaluate how well these cross sections can be measured for an unknown flux and generic detectors. We also demonstrate how to characterize and compare detector sensitivity. We show that cross sections can be measured to $\simeq ^{+65}_{-30}$% precision over $\sqrt{s} \simeq$ 4-140 TeV ($E_\nu = 10^7$-$10^{10}$ GeV) with modest energy and angular resolution and $\simeq 10$ events per energy decade. Many allowed novel-physics models (extra dimensions, leptoquarks, etc.) produce much larger effects. In the distant future, with $\simeq 100$ events at the highest energies, the precision would be $\simeq 15\%$, probing even QCD saturation effects.
