Reconstruction of proton decay events in a densely instrumented neutrino telescope-like detector

After successfully lowering IceCubes neutrino threshold to 10 GeV with its DeepCore infill-array, ideas arose to leverage the optically quiet Antarctic deep-ice to build an extremely densely instrumented, large-volume detector sensitive to MeV neutrinos. Among several interesting physics topics, such a detector would be able to pursue detection of proton decay. Using decays of protons into pi0 and positron, the talk presents the status of the reconstruction of such events via Cherenkov-ring identification. Different detector configurations are examined in order to determine the optimal design for the reconstruction.
