Reconstruction of Neutrino Events in IceCube using Graph Neural Networks

Understand

The IceCube Neutrino Observatory is a cubic-kilometer scale neutrino detector embedded in the Antarctic ice of the South Pole.

• In the near future, the detector will be augmented by extensions, such as the IceCube Upgrade and the planned Gen2 detector.
• The sparseness of observed light in the detector for low-energy events, and the irregular detector geometry, have always been a challenge to the reconstruction of the detected neutrinos' parameters of interest.
• This challenge remains with the IceCube Upgrade, currently under construction, which introduces seven new detector strings with novel detector modules.
