Description
Supersymmetry and Grand Unified Theories predict several nucleon decay modes with lifetimes between $10^{28}$ and $10^{39}$ years. The Deep Underground Neutrino Experiment (DUNE) will be able to test many of the predicted decay modes for lifetimes up to $10^{35}$ years. DUNE's far detector will comprise four 10-kiloton Liquid Argon Time Projection Chambers (LAr TPCs) installed 1475 meters underground. Its design combines high precision calorimetry with an exposure of several 100 kiloton-years in a low-background environment, which makes it especially suitable for proton decay searches via $p \rightarrow K^+ + \bar{\nu}$. I will present a sensitivity study for this channel in DUNE, using a fully simulated and reconstructed signal and atmospheric neutrino background sample in a 10-kiloton dual phase LAr TPC.
