Charles Univesity physicists take part in ATLAS experiment ****************************************************************************************** * ****************************************************************************************** This year’s Nobel Prize for Physics has been awarded to Francois Englert and Peter W. Higg theoretical discovery of a mechanism contributing to our understanding of the origin of th subatomic particles, recently confirmed by the discovery of the predicted fundamental part ATLAS and CMS experiments on the LHC accelerator at CERN. The experimental confirmation of the existence of the Higgs boson was the discovery of the of the so-called Standard Model of the microcosm, requiring the efforts of thousands of sc existence of the boson was proved in two separate experiments, ATLAS and CMS, over the cou The international team of 300 physicists working at the ATLAS detector included more than and students from the Czech Republic. Specialists from the CU Faculty of mathematics and P Academy of Sciences and the Czech Technical University (CTU) were amongst the founding mem experiment, contributing from the start to the design and construction of the detector. Th currently focusing on the operation and modification of part of the ATLAS detector, and ch analysis of gathered data on proton collisions within the LHC accelerator. Several special involved in measuring the properties of the Higgs boson. “In its simplest form, the BEH theory can, with the introduction of a single new particle, Higgs boson) explain the large-scale values of the so-called intermediate bosons W and Z, discovered 30 years ago, also at CERN,” said the chairman of the Committee for the Coopera Republic with CERN, docent RNDr. Rupert Leitner, DrSc. The first reports of the discovery boson, which is about 130 times heavier than a proton, were announced by the ATLAS and CMS last July. Particle decay found during the study of proton collisions within the accelerat the long sought-after Higgs boson may have been found. Further experimental data gathered of last year proved that other decay processes and properties of the new particle were in anticipated properties of the Higgs boson. “The existence of the Higgs boson has now been different experiments, ATLAS and CMS, and within each of these through around a thousand d for three different pairs of particles,” added docent Leitner. Professor RNDr. Jiří Hořejší called the discovery of the Higgs boson the last milestone on confirming the theories of the so-called Standard Model of weak electrical interactions. “ observed really is the Higgs boson, then it will be the first time that an elementary part of 0 has been observed, which is, in itself, remarkable. Secondly, the exchange of the Hig represents a certain, specific interaction, not identical to any of the four fundamental f observed. We could therefore, in this sense, also talk of the discovery of a new ‘fifth in Professor Hořejší. “The discovery of the Higgs boson required an enormous effort on the part of many people, ATLAS experiment, Czech scientists made a worthy contribution to this global effort,” said Kupčo from the Institute of Physics of the Czech Academy of Sciences on the project, which supported by the Czech Ministry for Education, Youth and Sports since 2004.
