Description
We propose a multi-purpose neutrino observatory comprising two very large detectors solving different problems at the intersection of particle physics, astrophysics and Earth science. Baikal-GVD will work jointly with KM3NET and IceCube in the Global Neutrino Network, aiming at the detection and study of high-energy astrophysical neutrinos. The new Baksan neutrino telescope (NBNT) will inherit from its smaller precursor, Borexino, but will become the only large-scale neutrino detector geographically located in Europe. Thanks to the unique low-background conditions at Baksan, determined by a combination of depth and of location far from artificial nuclear reactors, it will be the best instrument in the world to measure the CNO solar neutrino flux, at the same time addressing a wide range of other problems.
