DESCRIPTION:The recent observation of two PeV events at IceCube\, followed
  by an additional 26 events between 20 -\n300 TeV\, has spurred a lot of i
 nterest on its origin and underlying spectral shape. Several astrophysical
 \nsources have been considered\, and from a particle physics point of view
 \, many exotic phenomena have been invoked to explain these events. Assumi
 ng a simple astrophysical power law spectrum\, we scrutinize the Standard 
 Model (SM) expectations carefully\, including the theoretical uncertaintie
 s\, and find that the SM neutrino-nucleon interactions are sufficient to a
 ccount for all the observed events so far. However\, with more statistics\
 , this could provide a unique test of the SM up to the highest energies ev
 er observed in Nature\, and might lead to important clues to New Physics.
