If there is the elusive Higgs boson, a particle that scientists are striving to find to complete the Standard Model of Particle Physics, the mass range is between about 115 and 130 gigaelectronvolts (GeV). This is a step forward “significant” in the search, according to researchers at CMS and ATLAS experiments today presented data at the headquarters of the European Organization for Nuclear Research (CERN). The scientific community is confident that the end of 2012 remains unclear whether or not the Higgs boson.
“ATLAS and CMS collaborations (the two largest experiments of the Large Hadron Collider or LHC) have managed to exclude the data collected in 2011 Higgs masses in the standard model above about 127 GeV, which represents a breakthrough in this search “, explains to SINC Juan Alcaraz, principal investigator of CIEMAT in the CMS.
Cintíficos experiments ATLAS and CMS were presented today at a seminar at CERN, the status of your search for the Higgs boson predicted by the Standard Model of Particle Physics.Their results are based on the analysis of a data amount considerably higher than the results presented at the conference last summer, enough to make significant progress in the search for the Higgs boson, but not to make a strong statement on the existence of this elusive particle.
“In the mass range 114-127 GeV, both collaborations are slight excess, particularly on channel two-photon decay and mass in the 124-126 GeV, but the amount of data collected to date is insufficient to to determine if this really is the Higgs particle or simple statistical fluctuations somewhat higher than expected, “says Alcaraz.

Everything You Always Wanted to Know About boson Higgs never dare to ask …
God particle, the origin of the mass of all other particles, the main purpose of the LHC, missing piece of the standard model … These qualifiers are enough to feed number of press headlines and news articles of world whole. However, they do not explain what this really famous particle. CERN in Bulletin part in the theoretical discovery of the Higgs boson before the LHC does so in practice (if it exists!).
