Neutrino-nucleus Coherent Scattering with Reactor and Solar Neutrinos

Neutrino-nucleus (νN) elastic scattering has been observed with neutrinos from decay-at-rest pions, in which the quantum-mechanical coherency effects are only partial. To probe full coherency, studies of νN scattering with lower energy neutrino sources would be necessary. We will review various projects pursuing this goal with solar (the "neutrino floor" to direct WIMP searches) and reactor neutrinos, discussing their experimental challenges, status and prospects.
