摘要：
We propose the concept of neutrino colliders, which utilize high-energy neutrino beams to probe the Standard Model with unprecedented reach and to search for physics beyond it. The concept encompasses fixed-target neutrino–ion collisions at terrestrial accelerator facilities, neutrino interactions observed in large-volume neutrino telescopes, and neutrino-lepton collisions arising at future muon colliders. The incident neutrino energies span an enormous range, from the GeV scale up to 1012 GeV. In particular, collisions between cosmic neutrinos with energies above 100 PeV and nucleons in terrestrial detectors can achieve center-of-mass energies exceeding the 14 TeV limit of the Large Hadron Collider (LHC). Using recently predicted and measured high-energy and ultra-high-energy neutrino fluxes from the IceCube Collaboration and KM3NeT Collaboration, we estimate the mass-scale sensitivities to representative new-physics scenarios at 1–30 km3 neutrino telescopes, including TRIDENT, HUNT and NEON. In addition, neutrino partons radiated from future high-energy muon beams effectively realize TeV-scale neutrino–lepton collisions, providing sensitivity to W'/Z' gauge bosons as well as Standard Model Effective Field Theory (SMEFT) operators.
