Description

The DARWIN project aims to build and operate a next-generation observatory for dark matter and neutrino physics. The detector features a dual-phase time projection chamber (TPC) with a proposed active target of 40 t of liquid xenon (LXe), built underground with carefully select materials. It aims to achieve a low-energy threshold and an ultra-low background level, enabling the search for a wide range of neutrino interactions and properties. These include the study of solar neutrinos, both via electron scattering with the measurement of the low-energy solar neutrino flux of $pp$, $^{7}Be$, $^{13}N$, $^{15}O$, and $pep$ neutrinos and nuclear scattering with the precision measurement of the $^{8}B$ solar neutrino flux. Moreover, the presence of $^{136}Xe$ in the active volume allows the search for neutrinoless double beta decay of this isotope, resulting in a projected half-life sensitivity of $2.4⋅10^{27} yr$ after 10 years of operation. In addition, given its large target mass and low-energy threshold, DARWIN will be sensitive to neutrinos coming from supernova bursts above 50 kpc and actively contribute to the multimessenger astronomy community.
This contribution will cover the current DARWIN project design, status, and physics goals, focusing on the neutrino physics reach of this next-generation LXe detector.
