Abstract
Supported by the recent detection of a TXS 0506+056 blazar neutrino with an energy in the TeV-PeV range detected by the IceCube experiment, a probe of a new physics scale LNP related to high-energy cosmic neutrinos is provided. At Standard Model energies, the effect of the underlying physics LNP is first investigated. Then, the recorded IceCube-170922A data is used to approach the scale of such a new physics which lies under the Grand Unified Theory scale 10^25eV.
