Description
As an underground multi-purpose neutrino experiment with a detector of 20 kton liquid scintillator, Jiangmen Underground Neutrino Observatory (JUNO) is competitive with and complementary to the water-Cherenkov detectors on the search for the diffuse supernova neutrino background (DSNB). We employ the latest information on the DSNB flux predictions and investigate in detail the background and its reduction for the DSNB search at JUNO. The dominant background is from the neutral-current (NC) interaction of atmospheric neutrinos with $^{12}$C nuclei, whose uncertainty is carefully evaluated from both the spread of model prediction and an envisaged in situ measurement. In addition, the background suppression techniques with the pulse shape discrimination (PSD) and triple coincidence (TC) cuts are carefully studied. In this poster, we will present the prospects of detecting the DSNB in JUNO.
