Physics Briefings

Di-photons in the spotlight

16th June 2016 – The ATLAS collaboration has now released the final results on the search for new physics in the di-photon channel using 2015 data.

Something went bump in the night

16th June 2016 – 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.

A peek inside the proton…

15th June 2016 – 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.

Weighing in on the top quark mass

15th June 2016 – ATLAS has released a new precise measurement of the mass of the top quark, the heaviest known elementary particle.

Stacking the building blocks of the 2016 ATLAS physics programme

13th June 2016 – 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.

The search for the dark side of the Universe

13th April 2016 – 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.

Wanted: SUSY particle still at large

7th April 2016According 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.
