July 3, 2012 at 20:05Did CERN discover the Higgs boson? (UPD)
Undoubtedly, judging by the serious technical results that are literally on the very front line of modern physics, according to the articles of a popular publication, is a rather dubious exercise, so you have to be careful.
To be more precise, the situation is as follows: the European Organization for Nuclear Research (CERN), according to a press release issued on June 22, intends to hold a scientific seminar on July 4, the purpose of which is to publicly report on the search for the Higgs boson over the past year. The essence of the research was the accumulation and analysis of data from the ATLAS and CMS experiments.(code names of the main experiments conducted at the Large Hadron Collider). In December 2011, the results were presented, according to which the Higgs boson, if it exists, has energy in the region of 116-131 GeV - this was announced by the ATLAS collaboration (i.e., a group of physicists), or 115-127 GeV, according to the CMS collaboration. Thus, it was concluded that both experiments indicate the possible presence of a particle in the range 124-126 GeV.
In other words, CERN employees express themselves quite prudently, avoiding cheap sensations. However, gazeta.ru cites the following words of the head of the RDMS-CMS (Russia Dubna Member States - CMS) collective of the Large Hadron Collider Igor Golutvin:
If we return from the mentioned press release again, then again we can note much more cautious words of CERN Director for Research and Computing Sergio Bertolucci:
One way or another, a statement will be made on Wednesday, which will be devoted to, although widely publicized, but still fundamental research. You can follow the press conference online - the webcast will be available here .

UPD: According to news reports, the Higgs boson is indeed found.
A Gazeta.Ru source in the CMS collaboration confirms that the Higgs boson is open. This was announced the day before the official announcement by several sources in different countries. Today it became known that Peter Higgs was invited to tomorrow's seminar. The conclusions from the discovery are not clear - either this is the last “brick” of the model existing today, or it is the door to the unknown abysses of the “new physics”.

We all agreed to remain silent until tomorrow, when everything will be announced at the seminar, but the British colleagues could not stand it and told everything today in their press ... The essence is this: two experiments - CMS and ATLAS - observed the same, let's call it a particle, although it can be called a state . The mass of this particle is approximately 125 GeV. The level of statistical significance is 5 sigma (this is a statistical standard deviation). In other words, the probability that a discovery is erroneous is one hundredth of a percent.
If we return from the mentioned press release again, then again we can note much more cautious words of CERN Director for Research and Computing Sergio Bertolucci:
Compared to last year, we really more than doubled the amount of accumulated data. Now there is enough of them to check the trends that we set in 2011, whether they really are preserved.
One way or another, a statement will be made on Wednesday, which will be devoted to, although widely publicized, but still fundamental research. You can follow the press conference online - the webcast will be available here .

UPD: According to news reports, the Higgs boson is indeed found.
Scientists at the European Center for Nuclear Research (CERN), during their research, achieved a probability of the Higgs boson of almost 5 points on the sigma scale, which corresponds to the status of a scientific discovery. This was stated at a seminar taking place at these hours in CERN headquarters, a representative of the experimenting group of scientists from "CMS" Joe Incandela.
