ATLAS Briefings
Di-photons in the spotlight
– The ATLAS collaboration has now released the final results on the search for new physics in the di-photon channel using 2015 data.Read more →
Something went bump in the night
– 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.Read more →
A peek inside the proton…
– 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.Read more →
Weighing in on the top quark mass
– ATLAS has released a new precise measurement of the mass of the top quark, the heaviest known elementary particle.Read more →
Stacking the building blocks of the 2016 ATLAS physics programme
– 2016 is set to be an outstanding year for the ATLAS experiment and the Large Hadron Collider. We’re expecting up to 10 times more data compared to 2015, which will allow us to make precise measurements of many known physics processes and to search for new physics.Read more →
The search for the dark side of the Universe
– ATLAS scientists have just released a new publication with results based on an analysis of the early Run 2 data collected in 2015 using 13 TeV proton-proton collisions.Read more →
Wanted: SUSY particle still at large
– According to classical electrodynamics, the electromagnetic energy (and mass) of a point-like electron should be infinite. This is of course not the case! The solution of the riddle is antimatter - the ‘vacuum’ around every electron is filled with a cloud of electrons and anti-electrons and the combined energy turns out to be finite.Read more →
Searching beyond the Standard Model with photon pairs
– The ATLAS Collaboration uses two selections in this search, one optimised for Higgs-like particles that are expected to have a strong signal compared to background with both photons in the central region of the detector (the “spin-0” selection) and a second optimised for graviton-like particles (the “spin-2” selection) which often have at least one photon close to the LHC proton beam axis.Read more →
Chasing after elusive B meson decays into muons
– Almost four years following the discovery of the Higgs boson, LHC experiments are now more than ever exploring the possibility of new particles and new effects beyond the Standard Model.Read more →
Are there more Higgs bosons?
– The results presented by the ATLAS collaboration during the Moriond Electroweak 2016 conference set new limits on a potential extended Higgs sector.Read more →
