摘要: Future large liquid-scintillator detectors can be implemented to observe neutrinos from a core-collapse supernova (SN) in our galaxy in various reaction channels: (1) The inverse beta decay ν¯¯¯e+p→n+e+; (2) The elastic neutrino-proton scattering ν+p→ν+p; (3) The elastic neutrino-electron scattering ν+e−→ν+e−; (4) The charged-current νe interaction νe+12C→e−+12N; (5) The charged-current ν¯¯¯e interaction ν¯¯¯e+12C→e++12B; (6) The neutral-current interaction ν+12C→ν+12C∗. The less abundant 13C atoms in the liquid scintillator are also considered as a target, and both the charged-current interaction νe+13C→e−+13N and the neutral-current interaction ν+13C→ν+13C∗ are taken into account. In this work, we show for the first time that a global analysis of all these channels at a single {liquid-}scintillator detector, such as Jiangmen Underground Neutrino Observatory (JUNO), is very important to test the average-energy hierarchy of SN neutrinos and how the total energy is partitioned among neutrino flavors. In addition, the dominant channels for reconstructing neutrino spectra and the impact of other channels are discussed in great detail.
