Description
The next generation of experiments searching for rare-physics events with increased sensitivity will require precise predictions of cosmogenic backgrounds. Recent high quality deep underground measurements for cosmogenic neutrons in large liquid scintillator targets were used to study the FLUKA simulation package for this purpose. The results and conclusions drawn from a detailed benchmark comparison with data from the Borexino experiment were reported recently and will be summarized with focus on identified issues. Improved physics models already implemented in a beta-version of the FLUKA code, which will be publicly available with the upcoming code release, address the more important identified issues. A careful evaluation of the improved predictions is ongoing. However, the agreement between FLUKA simulation results and the Borexino experimental data is quite excellent at this point. Preliminary new findings will be presented.
Summary
