Fluorescence decay-time constants in organic liquid scintillators

Understand

The fluorescence decay-time constants have been measured for several scintillator mixtures based on phenyl-o-xylylethane (PXE) and linear alkylbenzene (LAB) solvents.

• The resulting values are of relevance for the physics performance of the proposed large-volume liquid scintillator detector LENA (Low Energy Neutrino Astronomy).
• In particular, the impact of the measured values to the search for proton decay via p -> K+ antineutrino is evaluated in this work.
