In St. Petersburg, opened one of the major scientific conferences of this year - "Physics of the Large Hadron Collider”
Representatives of the four LHC collaborations during the week (conference runs from 31 August to 5 September) will present the results obtained after the launch of the LHC at full capacity in the 13 TeV, which was achieved after almost two-year break for repairs and upgrades.
Conference LHCP2015 notable because earlier work at CERN, the LHC is a part of which was aimed at testing theoretical predictions - mainly, with regard to the Standard Model of elementary particles. Those discoveries that were made in the 80s, confirmed the validity of the Standard Model, and the last brick was the discovery of the Higgs boson in 2012. The goal of the new launch of the LHC at full capacity in the spring of this year - not confirm the theoretical predictions and the discovery of something new out of this theory, in the so-called new physics. The experiments, which will take place in the coming years, should make it clear whether there is a physics beyond the Standard Model.
Physicists have high expectations of future results, which will be available at that level of energy. Corresponding Member of the Russian Academy of Sciences, head of the St. Petersburg Institute of Nuclear Physics Research Center "Kurchatov Institute" in the CMS collaboration and LHCb Alexei Vorobyov said that any new quality appears with increasing energy. Although the LHC has just reached a new level of 13 TeV, already have projects to achieve energy of 100 TeV. "The whole scientific world is waiting for it to happen. While significant results can only boast collaboration LHCb. The researchers recorded the new pentaquark like state that had been predicted theoretically. This observation was reported six months ago ", - commented on the conference, Dr. Sc. n., Professor of St. Petersburg State University (Department of high-energy physics and elementary particles) Sergey Afonin.
Apart from the results obtained after the restart of the collider, at the conference were first summarizes the results of the study of the Higgs boson in the three years that have passed since its discovery. By combining their data, ATLAS and CMS collaborations were able to provide the most complete picture of how the boson formed decomposes and interacts with other particles. All data are in agreement with the predictions of the Standard Model, and become a reference point for new research. According to the press-secretary of the CMS collaboration Tiziano Kamporezi, quoted by resource phys.org, a generalization of the two experiments conducted by two teams of scientists on two different detectors, which include more than 4,200 parameters, it became a real challenge. But this work makes it possible to see the Higgs boson from all possible angles.
St. Petersburg became the owner of the largest physical conference is not accidental. The contribution of Russian researchers in elementary particle physics can not be overestimated. At CERN, the world's largest high-energy physics laboratory, employs approximately 10,000 people in 80 countries, nearly 800 of them - Russian scientists and engineers, whose contribution to the development of the LHC project was and remains very significant. "Ideas, equipment and innovations that brought Russian, are unparalleled," - he said during a press conference which was given by representatives of the Organizing Committee LHCP2015, Deputy Director General of CERN, Sergio Bertolucci Science.
The organizers of the conference "Physics of the Large Hadron Collider - LHCP2015» is the National Research Centre "Kurchatov Institute", Petersburg Nuclear Physics Institute (PNPI SIC CI), the Institute of High Energy Physics (IHEP SIC CI), Institute of Theoretical and Experimental Physics (ITEP SIC CI) Joint Institute for Nuclear Research (JINR), St. Petersburg State University (State University) and St. Petersburg Polytechnic University (SpbPU)
