Supersymmetry at the South Pole

The recent observation of high-energy neutrinos at the IceCube neutrino telescope has opened a new window to the Universe.  Understanding all aspects of these events is very important for both astrophysics and particle physics ramifications.  We will discuss how the IceCube data can be used to probe a well-motivated new physics scenario, namely, R-parity violating supersymmetry. We will also relate this to two recent anomalies at very different energy scales: (i) upgoing EeV events observed by the ANITA balloon experiment and (ii) hints of lepton flavor universality violation in rare B-meson decays.
