In NSU built a prototype detector for dark matter

In the laboratory, cosmology and elementary particle physics, Novosibirsk State University have designed a prototype detector to search for dark materii.Kak the press service of the NSU, the laboratory cosmology and elementary particle was created in 2011 by means of megagranta the Government.

  

Says Alexander Dolgov, head of the Laboratory:

— Made a big step with the construction of the detector. From a small model, we have moved to action prototype. This is a huge job. In the theoretical part of the research, we are working in two directions: cosmology and astrophysics. In particular, our staff proposed a new method for determining the cosmological distances, it is important to study the properties of dark energy. Accelerated expansion has been found, in particular, on the discovery that distant supernovae are the so-called type 1a are dimmer than predicted by standard cosmology, so they go ahead and expanding faster than expected. For this conclusion, it is important to know how far away the supernova. Conventional methods for determining distances are multi-stage and may contain serious systematic errors. Our theorists proposed a new way, free from these problems. Invited to watch another type of supernova, which shed their skin several times, and then we can estimate the distance to them, seeing the size of the discharged shells. This is a direct way, and it allows you to determine the expansion rate of the universe itself. In addition, we are trying to understand what is the carrier or carriers of dark matter by studying the observable consequences of any of its forms.

However, while Novosibirsk scientists can not detect dark matter. "First of all, you need a much larger volume of the detector. In addition, it is necessary to work in a place protected from cosmic radiation ", — said the debt. The scientist gave the example of Italian researchers who work in the center of Italy, in a cave under a mountain of Gran Sasso. There's only held, but not confirmed by experiment, where are the signal that can be interpreted as the registration of dark matter.

Alexander Dolgov said that in the lab are hoping for an extension of the grant, in September will be here auditor to evaluate the result. According to the results of theoretical and experimental research laboratory was published about 20 scientific papers and reports have been read by many international conferences.
