Abstract

Abstract: The recent observation of 37 ultra-high energy (UHE) neutrino events at IceCube has spurred a lot of interest in the scientific community. From a particle physics point of view, several exotic phenomena have been proposed to explain the data. For a reliable interpretation, it is however important to first scrutinize the Standard Model (SM) expectations carefully, including all known theoretical and experimental uncertainties. In this talk, we discuss the compatibility of the 3-year IceCube dataset with some well-motivated flavor and spectral compositions of the astrophysical flux within the SM framework, and show that the SM interactions are sufficient to explain the current data within the known uncertainties. Using this result, we derive constraints on some New Physics scenarios, which are otherwise difficult to probe at the LHC or other existing low-energy experiments.
