ATLAS physicists have been eagerly searching the collected data for evidence of the production of the supersymmetric top quark (squark). Recent ATLAS results feature five separate searches for this elusive particle.
The ATLAS experiment has been searching for the process in which a pair of top quarks is produced, where one is a “virtual” particle that emits a Higgs boson on the way to becoming a “real” particle. This process is referred to as ttH production after the particles that are produced.
The nature of dark matter remains one of the greatest mysteries in physics. While extraordinary, the Standard Model can not explain dark matter, whose existence is well established by cosmological measurements.
Results using record-breaking 2016 data will be presented at the International Conference on High Energy Physics (ICHEP) in Chicago, 3-10 August.
For a long time, physicists have assumed that space-time has four dimensions in total – three of space and one of time – in agreement with what we see when we look around us. However, some theorists have proposed that there may be other spatial dimensions that we don’t experience in our daily lives.
The ATLAS collaboration has now released the final results on the search for new physics in the di-photon channel using 2015 data.
ATLAS has published hundreds of studies of LHC data, with the Higgs boson discovery being perhaps the best known. Amongst the Run 1 searches there was one which stood out: the diboson excess.
When the protons from the LHC collide, they sometimes produce W and Z bosons, the massive carriers of the weak force responsible for radioactive decays. These bosons are produced in abundance at the LHC and ATLAS physicists have now precisely measured their production rates using 13 TeV proton-proton collision data recorded in 2015.
ATLAS has released a new precise measurement of the mass of the top quark, the heaviest known elementary particle.
The Large Hadron Collider Physics (LHCP2016) conference kicked off today in Lund, Sweden. Held annually, the LHCP conference is an opportunity for experimental and theoretical physicists to discuss results from across the high-energy physics community. From Standard Model Physics and Heavy Ion Physics to Supersymmetry and other Beyond Standard Model investigations, the conference unites the disciplines to examine recent progress and consider future developments.
