Abstract
We explore the bound neutrons decay into invisible particles (e.g.,
n→ 3 ν or nn → 2 ν) in the JUNO liquid scintillator
detector. The invisible decay includes two decay modes: n → inv and nn → inv. The invisible decays of s-shell neutrons in
^12 C will leave a highly excited residual nucleus. Subsequently, some
de-excitation modes of the excited residual nuclei can produce a time- and
space-correlated triple coincidence signal in the JUNO detector. Based on a
full Monte Carlo simulation informed with the latest available data, we
estimate all backgrounds, including inverse beta decay events of the reactor
antineutrino ν̅_e, natural radioactivity, cosmogenic isotopes and
neutral current interactions of atmospheric neutrinos. Pulse shape
discrimination and multivariate analysis techniques are employed to further
suppress backgrounds. With two years of exposure, JUNO is expected to give an
order of magnitude improvement compared to the current best limits. After 10
years of data taking, the JUNO expected sensitivities at a 90
are τ/B( n → inv ) > 5.0 × 10^31 yr and
τ/B( nn → inv ) > 1.4 × 10^32 yr.
