** Abstracts:
Nuclear reactors provide an intense source of electron antineutrinos with a well-understood flux, useful for both applied and fundamental studies. The JINR reactor-based neutrino program investigates these properties using complementary approaches, targeting oscillations, neutrino electromagnetic properties, and coherent scattering.
The DANSS experiment, operating just 10 m from a 3 GWth power reactor, has accumulated one of the world’s largest IBD data sets, enabling precision reactor monitoring and stringent constraints on sterile neutrino oscillations at short baselines.
Two other experiments at the same site are the GEMMA and νGeN experiments. GEMMA used a low-background HPGe detector to search for anomalous electromagnetic interactions and set one of the best limits on the neutrino magnetic moment. The νGeN project employs a sub-keV-threshold Ge detector to search for coherent elastic neutrino-nucleus scattering (CEνNS), recently improving the global limits for reactor-based CEνNS.
Results from these experiments will be presented, along with a description of the experimental techniques that enable sensitive measurements near a commercial power reactor, and a discussion of the prospects for the DANSS-2 upgrade.
