TOMSK, Oct 21 – RIA Tomsk. Scientists of Tomsk Polytechnic University (TPU) together with experts from the European Organization for Nuclear Research (CERN) are engaged in searches of a dark boson – a hypothetical intermediary particle which can be a potential candidate for a role of dark matter, the press service of the higher education institution reported on Wednesday.
It is noted that after discovery of Higgs boson on the Large Hadron Collider in 2012 the central problem in physics of elementary particles is research of an origin and nature of dark matter making the significant contribution (about 23%) to the mass of our Universe. The new particle is similar to a usual photon – light quantum transferring electromagnetic interactions between elementary particles, but, unlike it, it has a weight.
"In May scientists of Tomsk Polytechnic University together with colleagues from the leading institutes, universities and scientific centers of Russia, Chile, Switzerland and Germany within the experiment which received the name P348 began researches on search of a dark boson – a potential candidate for a role of dark matter – on SPS in the European Organization for Nuclear Research ", – it is told in the message.
In 2014 the Russian scientists suggested to make an experiment on search of easy dark matter on the proton supersynchrotron (accelerator) of SPS. Polytechnicians together with colleagues carried out assembly, and then started a hadron calorimeter for the experimental P348 installation. At the same time the group was engaged in modeling of the expected experimental data and start of electronics for reliable providing a record of data from the detectors.

"The trial session on the accelerator in which scientists of TPU took part, took place from September 23 to October 7. After experiment they started processing and the analysis of the obtained data", – the press service added.
After the first session on SPS scientists will draw conclusions on degree of readiness and compliance of a component of the detector to the experiment purposes, receive the first physical result on the basis of a real assessment. If trial experiment takes place successfully, scientists will transfer submission of the further engineering design to SPSC committee and will continue work on the project.
Founded in 1896, TPU is the oldest technical college in Asian part of Russia. According to the last national rating researches, TPU is included in the first top ten higher education institutions of Russia. There are 11 scientific and educational and educational institutes, 97 departments in TPU. For more than century history the university trained over 160 thousand experts.
CERN (Conseil Européen pour la Recherche Nucléaire) is the largest international scientific organization of Europe in the field of nuclear physics. It is located in Switzerland. Large number of opening was made here, in particular, Higgs boson is discovered. It operates the Large Hadron Collider.
