The full study of the Universe is confirmed


The international group of the physicists working at the Large Hadron Collider as a part of collaborations of ATLAS and CMS (CERN) for the first time observed disintegration of Higgs boson on two b-quarks (bottom-quark). This opening confirms the Standard model describing properties of elementary particles again. Scientists have also not found the evidence of possible existence of New physics which could explain possible shortcomings of the existing theory. It is reported in the press release on Phys.org. In accelerators of particles Higgs boson arises at head-on collision of two protons when there is a merge of gluons — kinds of the bosons which are responsible for interaction between quarks and their deduction in a proton. From gluons the u-quark and an anti-u-quark from which in turn there is a short-lived Higgs boson results. After that it almost at once breaks up, at the same time education an electron - positron couples, photons, a muon and anti-muon is possible. Materials on teme00:04 — on August 4, 2017 It is vigorous voshyucheny have deceived time and caught imperceptible prizrakasoglasno to prediction of Standard model, disintegration on b-quarks happens in 60 percent of cases. Other types of disintegration of Higgs boson are well distinguishable against the background of "noise" while emergence of a b-quark and b-anti-quark masks other processes which lead to emergence of bottom-quarks. For example, collision of protons creates heavy rain from subatomic particles, including required. Therefore for identification of the predicted event physics needed to save up statistics for five standard deviations (equivalently to probability of nonrandom result in 99,97 percent), having analysed hundreds of thousands of disintegrations of particles at a proton - proton collisions. New data have been obtained at two runs of bunches of charged particles on a 27-kilometer ring of the Large Hadron Collider. Collisions of protons happened at energiya of 7, 8 and 13 teraelectronvolts. Then scientists have analysed information, considering by-products at interaction of particles. It has allowed to find not only disintegration of Higgs boson on bottom-quarks, but also to confirm that his speed corresponds to the value predicted by Standard model. Higgs boson participates in the mechanism (Higgs's mechanism) of emergence of mass of such fundamental particles as carriers of weak interaction (W-and Z-bosons) and also the lack of mass of rest at a gluon and a photon defines. In spite of the fact that opening of this particle and studying of its properties confirms Standard model, there are problems (for example, asymmetry of matter and anti-matter in the Universe or incompatibility with the theory of relativity) which from her position don't manage to be explained. At the same time on accelerators of particles hints on existence of New physics still haven't been received. Some scientists consider that the New physics doesn't exist at all (or it in principle isn't observed), and at the moment almost everything that can only be known is known of the Universe.
