First beam splashes delivered by the LHC accelerator at CERN were observed by the two major experiments ATLAS and CMS. After almost two years of shutdown filled by accelerator and detectors upgrades, a new Run 3 of the LHC commences.
The observation of associated production of the top quark pair and the Higgs Boson is a process where direct interaction of these two heaviest particles of the Standard model of elementary particles comes into play. The production of the Higgs boson is accompanied with the top quark pair creation only in about 1% of events and for the observation of this process data from several decay channels have been combined.
The particle physics group at JLO is mainly bound to the CERN-ATLAS experiment at the LHC accelerator at CERN. While in the past JLO contributed to the CERN facilities with several deliveries of optical technologies, today the the involvement is of a more profound nature.
Geneva, 14 August 2017. Physicists from the ATLAS experiment at CERN have found the first direct evidence of high energy light-by-light scattering, a very rare process in which two photons – particles of light – interact and change direction.
