Neutrino Topology Reconstruction at DUNE and Applications to Searches for Dark Matter Annihilation in the Sun

Understand

We consider a new technique for neutrino energy and topology reconstruction at DUNE.

• In particular, we show that when the direction of the incoming neutrino is known, one can use the measured directions of the outgoing leptonic and hadronic particles to reconstruct poorly-measured quantities, such as the hadronic cascade energy.
• We show that this alternative technique yields an energy resolution which is comparable to current reconstruction methods which sum measured energies.
• As a proof of concept we apply this new reconstruction method to a search for dark matter annihilation in the Sun.
