Probing strong dynamics with cosmic neutrinos

Triggered by the IceCube detection of astrophysical neutrino candidates in the range of PeV energies, we propose to investigate the sensitivity of future South Pole neutrino-detection experiments to the neutrino-nucleon cross section. By using the combination of up- and down-going data of neutrinos, sensible to neutral current processes one can disentangle particle physics from astrophysics and constrain the neutrino interactions.In particular, we show that IceCube-Gen2 will be able to determine the neutrino-nucleon cross section with a precisión comparable to the perturbative QCD informed by collider data and eventually to detect new physics.
