Physics Opportunities of Large Liquid Scintillator Detectors (II)
Helmholtz Institute Mainz (HIM)

Charting the Path Beyond-Tonne-Scale and More Establishing sensitivity to neutrinoless double beta decay in the normal neutrino mass ordering is a defining goal for the coming decades. Organic liquid scintillator detectors offer a promising route to the large target masses and low backgrounds required, while enabling a rich additional physics program. Recent advances in detector technology, event reconstruction, and background discrimination motivate exploration of beyond tonne-scale sensitivity. At the same time, such detectors could also address DSNB, solar neutrinos, geo-neutrinos, and CP violation if deployed in a neutrino beam.
This is the Second Town Hall in a series of three town hall meetings, with the goal of converging on a shared path forward. The First Town Hall was held In June at UC Irvine. This second workshop will focus on the technical challenges of a future large-scale detector, ranging from basic scintillator properties and isotope loading via light sensing to electronics and event reconstruction. More information about registration and program will appear here soon.
