ԹϹ received funding from the Russian government to support the research conducted by the leading scientist Prof. Alexander Dolgov in the field of astronomy and astrophysics. Within this project the university set up the Laboratory of Cosmology and Elementary Particle Physics; the experiments at the laboratory are aimed at the development of methods for the direct detection of dark matter
Speaking about the laboratory, it continues to work on an instrument for direct detection of dark matter particles. The development of science never follows a prearranged plan. The laboratory obtained new results in 2015, but this is, figuratively speaking, “prenatal” development. We have made good progress in understanding how to create a technique to search for dark matter, but we are still very far from creating a real detector for real search.
One of the results of our work, though not direct, is that a group of scientists from the LCEP were invited to participate in the international DarkSide collaboration, which seeks to directly detect dark matter. Our results associated with the development of a prototype detector that uses liquefied noble gases such as argon or neon as a working fluid were recognized by the main organizers of the project—the Gran Sasso National Laboratory (Italy), and we were invited to the project.
Today researchers at major science centers worldwide are designing detectors to capture the elusive dark matter particles by applying different physical principles. Siberian physicists are looking for is the so-called cold dark matter: having been slow at first, its particles have now accelerated in the galaxy’s gravitational field to one thousandth of the speed of light. The range of possible masses of these particles is extremely wide: they might be both three orders of magnitude heavier and twelve orders of magnitude lighter than protons. The majority of physicists believe that dark matter particles must be quite massive, but the Siberian physicists follow another hypothesis, according to which these particles are only two to ten times more massive than protons. The best way to search for dark matter particles is to use detectors based on liquefied noble gases, such as argon or neon.
Currently, we are co-writing the project specifications together with the other participants. The collaboration seeks to build the DarkSide detector, which will be located in the Alps at a depth of several kilometers underground and contain 20 tons of argon. I hope that here we will find exciting research opportunities and take part in a real large-scale experiment, which, in my view, looks very promising.
