# Supersymmetric sphaleron configurations as the origin of the perplexing ANITA events

## TL;DR

This paper proposes that supersymmetric sphaleron transitions could explain the anomalous upward air showers observed by ANITA, suggesting a new BSM physics origin involving long-lived supersymmetric particles.

## Contribution

It introduces a novel explanation for ANITA events based on supersymmetric sphaleron configurations, linking astrophysical observations to beyond standard model physics.

## Key findings

- Supersymmetric sphaleron transitions can produce long-lived particles capable of traversing Earth.
- These particles can decay in the atmosphere to produce upward air showers.
- LHC detectors could potentially test this supersymmetric scenario.

## Abstract

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.
