The CERN particle found evidence of six times more massive than the Higgs boson – Hypertext

The reopening of the Large Hadron Collider (LHC, by its initials in English) promised great advances in the field of physics. The first major result of the CMS and ATLAS experiments after the discovery of the Higgs boson has been presented today in Geneva. The CERN has found evidence of an unknown particle to date and not predicted by the standard model. According to sources consulted by Hypertext , it is the “first indication of a particle not predicted by this theory, after that everything went as established by the standard model for years.” The signs point to a particle found for the first time would not meet the standard model of physics

The hypothetical particle discovered is six times more massive than the Higgs , since excess photon has been detected for a mass in the range between 747 and 760 GeV, when the Higgs boson is 125 GeV. Although scientists have not yet been able to determine which particle would be and whether it could be a statistical fluctuation, some experts suggest the possibility that there may be a particle associated with supersymmetry. Other experts, like Dr. Markus Nordberg, Department of Development and Innovation at CERN, have also suggested a Hypertext that the particle could be the first proof of the existence of parallel universes.

Today, the standard model explains the elementary particles and their interactions. The supersymmetry is a popular theory that aims to go a step beyond the standard model, it includes all the symmetries of its approach and adds another related quantum number known as spin. Thus, supersymmetry (SUSY called) provides for the existence of twice the number of particles predicted by the Standard Model.

With the start of the LHC to a wider range of energy (13 TeV), the researchers expected to find new particles in their collisions. The findings presented today is still preliminary, but it opens the door to a new era in the history of physics. As proposed by supersymmetry, there would be two more particles in the range now detected, so the particle discovered could meet one of the principles of SUSY . Experts contacted by this means remain cautious regarding the discovery, since the range is found at 760 GeV with 2.6 sigma excess of prediction, he commented Jim Olsen during the presentation the results of experiments CMS. In the case of the ATLAS experiment, the signs of this new particle have been to 747 GeV with 3.6 sigma excess of prediction, as explained Marumi Kado . This means that there is “evidence” of a new particle, but for CERN could confirm his findings, should detect the same peak with an excess of 5 sigma. The first hypothesis being considered on the nature of the particle are related to supersymmetry or the existence of parallel universes

“In 2011, for example, a particle that seemed to be the Higgs boson at 140 GeV found. However, the interval that was detected was three sigma and finally saw that it was a mere statistical fluctuation, “said an expert from CERN to Hypertext . After that false discovery 2011, CERN was able to discover a particle consistent with the Higgs months later, when detected with a mass of 125 GeV, proved decisive for François Englert and Peter Higgs received the Nobel Prize in Physics in 2013. In relation to the results now presented, physical prefers to remain cautious when discussing the evidence found by the CMS and ATLAS experiments, as more analysis is needed to confirm if this really is one of the particles predicted by supersymmetry. According to this same source says Hypertext , “a more cautious study lowers the number of sigma 1.2 and 1.9 on the CMS and ATLAS experiments respectively, but the fact that both of you see a excess in the same place is encouraging. ” In any case, the press officer of CERN stressed that “more data are needed” before confirming the preliminary results presented today, which have not yet been published in any scientific journal.

The hypothetical particle found CERN raises further questions for experts in particle physics. A failure to confirm its nature and the relationship you could have with supersymmetry or other assumptions of particle physics, the fact is that this new finding highlights the key role of the LHC tunnel to understand the world around us as we explained last September Dra. Fabiola Gianotti, who will assume the direction of CERN since January 1, 2016.
