Overview

• Use of wf-llh-reco reconstruction module for EHE
  cascade events
• Current EHE analysis plans
• Future Directions for EHE reconstruction

3
Using Wf-llh-reco for EHE cascade events

• EHE events ideal for waveform reconstruction
• Reliable energy reconstruction crucial Energy
  reconstructed at the same time as vertex.
• Good PDF taking into account the depth-dependent
  ice properties very important
• Non-contained events extremely important during
  early stages of deployment

4
Preliminary Results for an initial study of
non-contained events

• 500 JULIET Toy Cascades simulated with layered
  photonics tables.
• Cascades simulated from 1PeV to under 10EeV
• All cascades non-contained, randomly distributed
  from just outside full Icecube array to 0.5 km
  away.

7
Current EHE cascade reconstruction plans

• Implement Photonics (Johan Lundbergs Photorec
  functions) as the PDF in the reconstruction
• Look into cascade direction reconstruction
• Coordinate with Paolo Desiati for EHE event
  production.

8
Future Directions for EHE reconstruction

• Get reconstruction tables with a much larger
  active volume
• Look into reconstructing EHE tracks.
• . Then look at IceCube data and do EHE physics!
