  The ANITA experiment has observed two air shower events with energy ~ 500 PeV
emerging from the Earth with exit angles of ~ 30 degrees. We explain ANITA
events as arising from neutrino-induced supersymmetric sphaleron transitions.
These high-multiplicity configurations could contain a large number of
long-lived supersymmetric fermions, which can traverse the Earth and decay in
the atmosphere to initiate upward-pointing air showers at large angles above
the horizon. We comment on the sensitivity of new generation LHC detectors,
designed to searching for displaced decays of beyond standard model long-lived
particles, to test our model.
