论文摘要
中微子物理学的超高能量范围($ \ sim 10^{7} \,\ mathrm {gev} $)尚未检测到一个开放式景观,是一个有挑战和发现的挑战的开放景观。该范围内的中微子 - 核子横截面 - 具有摩托中心能量$ \ sqrt {s} \ gtrsim 4 \,\ mathrm {tev} $ - 是未探索现象的强大探针。我们提出了一个简单而准确的独立于模型的框架,以评估未知通量和通用探测器可以测量这些横截面的效果。我们还演示了如何表征和比较检测器灵敏度。我们表明,可以将横截面测量到$ \ simeq^{+65} _ { - 30} $%精度,$ \ sqrt {s} \ simeq $ 4-140 tev($e_ν= 10^7 $ - $ 10 $ - $ 10^{10} $ gev)具有模能和$ $ $ $ $ $ $ $ cemeq ecect ecect。许多允许新颖的物理模型(额外的维度,Leptoquarks等)产生更大的影响。在遥远的将来,具有最高能量的$ \ simeq 100 $事件,精度为$ \ simeq 15 \%$,甚至探测QCD饱和效果。
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 ($E_ν= 10^7$-$10^{10}$ 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.
