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.
