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 can derive constraints on

some New Physics scenarios, which are otherwise difficult

to probe at the LHC or other existing low-energy experiments.
