Grand Unified Theories (GUTs) are able to describe proton decay processes as they allow conversion reactions between quarks and leptons. The predictions of numerous supersymmetric GUTs are tested by searching for their main proton decay channel p → K+ν. Currently, the lower lifetime limit 5.9 × 1033 years has been set by the Super-Kamiokande Collaboration using a water-Cerenkov detector. By using a large liquid scintillator target mass, the Jiangmen Underground Neutrino Observatory (JUNO) aims to reach a sensitivity of 9.6 × 1033 years based on a total exposure of 200 kton · years.
JUNO’s detection efficiency can be further improved by modeling the signal structure of the decay kaon, especially it’s quenching behavior. The UniKaon experiment was designed to determine the kaon’s Birks’ factor by independent detection of the deposited energy and light output. In this talk, I present the current status of calibration and a full light propagation simulation.
This work is supported by the Clusters of Excellence Origins and PRISMA+ and the DFG Collaborative Research Center "NDM" (SFB1258).
