Abstract: The astrophysical neutrinos discovered by IceCube have the highest detected neutrino energies
? from TeV to PeV ? and likely travel the longest distances ? up to a few Gpc, the size
of the observable Universe. These features make them naturally attractive probes of fundamental
particle-physics properties, possibly tiny in size, at energy scales unreachable by any other means.
The decades before the IceCube discovery saw many proposals of particle-physics studies in this
direction. Today, those proposals have become a reality, in spite of astrophysical unknowns. We
will showcase examples of doing fundamental neutrino physics at these scales, including some
of the most stringent tests of physics beyond the Standard Model.
