Over the last two decades, the groundbreaking discovery of neutrino oscillations assured the leading role of neutrino physics in physical research. It is obvious that for the next two decades, neutrino physics will keep its crucial position in modern physics and search for answers to some fundamental questions about the structure of our Universe.
There are three research directions of the topic “Non-Accelerator Neutrino Physics and Astrophysics” with common approaches and resources: Double beta decay (NEMO-3&SuperNEMO, G&M&LEGEND and MONUMENT experiments); reactor antineutrino experiments (DANSS - search for sterile neutrinos, GEMMA - neutrino magnetic moment, vGEN – coherent elastic neutrino-nucleus scattering); astrophysics (BAIKAL–GVD - the deep-underwater neutrino telescope, EDELWEISS - search for dark matter). It should be emphasized that scientists from Dubna contribute a lot to these world-class experiments.
Neutrino geophysics has evolved to a separate discipline not so long ago. This rapidly developing branch of science at the intersection of geology, geophysics and particle physics examines the Earth’s interior by observing antineutrino fluxes produced by the decay of radioactive elements in the Earth’s crust and mantel. The contribution of radioactive decays to the total heat release of the Earth (radiogenic heat) determines the heat history of the Earth and restricts its geophysical models.
In direct searches for Dark Matter (DM) a technology developing by EDELWEISS experiment is arrays of Ge mono-crystal detectors operated at a temperature of few mK. A simultaneous measurement of ionization and heat signals allows efficient identification of nuclear and electron recoils. New results demonstrated the high relevance of cryogenic Ge detectors for the search of DM interactions producing eV-scale signals. The same technology and detectors will be applied for precision measurements of CEvNS in the region of full coherency in the Ricochet experiment (reactor neutrinos).
The article about the photography exhibition by Bair Shaybonov “Baikal. Neutrino Hunters” was published in the JINR weekly newspaper “Dubna: Science, Community, Progress”.
Do you want to enjoy amazing scenery of Baikal in winter? And to touch a glass sphere, an optical module to be submerged deep under the water? Visit the Exhibition Hall of the Mir Culture Centre where the photography exhibition “Baikal. Neutrino Hunters” has been recently launched. The photographer is a regular member of the International Baikal collaboration Bair Shaybonov. The exhibition is open till 30 October.

There is a wealth of ways to explain something. The main thing here is to be heard and understood. How to communicate science and make it clear and entertaining? Especially at the time of information superfluity when the brain tries to protect itself from unnecessary information with all its might, when internet users do not read texts any more, but just scan through them.
