There are, so far, 2 main LiquidO-based fundamental science projects being explored in close relation with the LiquidO project developments and some members of the consortium. Those are:
- SuperChooz possible future project is a new large flagship neutrino fundamental research project in Europe sensitive mainly to the reactor-neutrinos and solar-neutrinos, as well as geoneutrinos with the potential to measure core-collapse and remnant supernovae-neutrinos and key potential sensitivity to proton-decay searches. its feasibility exploration embodies the SuperChooz Pathfinder project (started in 2018). Within the scientific context of SuperChooz, there is also now the CLOUD experiment, tightly linked to AM-OTech innovation project (since 2020), specialised for fundamental research with reactor neutrinos since 2022.
- LiquidO-ββ: the exploration of the LiquidO technology potential to additionally address the compelling searches of ββ nuclear neutrino-less decay demonstrating the possible Majorana nature of the neutrino as well as enabling sensitivity to its absolute mass scale. This ambitious R&D (started around 2015) envisions the long-term explorations needed to address whether the LiquidO technology may be able to reach the most challenging normal mass ordering scale. Success is far from evident, due to the multiple challenges ahead, while the LiquidO detection framework seems to offer some of the necessary conditions, hence its potential role in this physics cannot yet be ruled out.
Other studies of the application of LiquidO technology to neutrino cases such as geoneutrino and GeV-neutrino detection (with and without accelerators as source) are ongoing within the LiquidO consortium. They are however not yet leading to any specific project proposals for concrete experimental scenarios.
