DESCRIPTION:The March 2018 report of two anomalous (Earth-emergent) e_cr ~
  0.6 EeVair showers by the ANITA collaboration has presented a severe puzz
 le of interpretation. Given existing limits on neutrino transient sources 
 and the diffuse neutrino flux\, these events are straightforwardly impossi
 ble under the Standard Model\, due primarily to the challengesof propagati
 ng SM particles of these energies along the observed extended path lengths
 . I will review the nature of the ANITAexperiment and the properties of th
 eir anomalous events\, and presentour arguments for the incompatibility of
  these observations with the Standard Model. I will also explore the possi
 ble existence of analog events among the highest-energy neutrinos of the I
 ceCube neutrinoobservatory. Together\, these observations encourage us to 
 consider the chief alternative\, that the ANITA Anomalous Events are media
 ted by arelatively long-lived Beyond Standard Model (BSM) particle. I will
  present our inferences as to the necessary properties of thisparticle\, w
 hich appear consistent (at least in part) with those predicted for the "st
 au" slepton in some supersymmetric modelsof the fundamental interactions. 
 LHC Run 2 data now under analysis may prove to be highly relevant in this 
 context.\n\nPlease join the meeting by clicking this link:  http://reunio
