Description
The IceCube Neutrino Observatory is a cubic kilometer Cherenkov light detector that also searches for signatures of particles beyond the standard model including fractionally charged particles. These are predicted to carry a fraction of the elementary charge, resulting in faint tracks in the detector.
To enhance the efficiency of detecting these faint signatures, we developed the novel Faint Particle Trigger (FPT). The FPT involves the analysis of isolated single hits which are not included in any other IceCube trigger. In the case of simulated faint exotic signatures and GeV-range leptons, these isolated single hits become the predominant hit type. The FPT significantly improves trigger efficiencies for signal simulations, concurrently increasing the event rate by approximately 0.5%.
The FPT commenced operations at the South Pole in November 2023. The development, processing chain for the new events and implications for analyses will be presented.
