Waiting for physics: Stable beams!

11th May 2018 – Following the first “beam splash” tests in early-April, the ATLAS experiment awaited the next milestone on the road to data-taking: "stable beams". This is when the LHC proton beams are aligned, squeezed, focused and finally steered to collide head-to-head. It is an important test, as it allows us to verify that the collision mechanism is ready to take data that are good for physics studies.

Waiting for physics: Splashing beams

10th May 2018 – Each year, around mid-spring, the giant LHC accelerator wakes up from its winter maintenance and gets ready for a new feverish period of data taking. But before smashing protons once again, some tests have to be done, to check that everything is in order and that the machine can accelerate and collide particles properly, as it did before the shutdown.

Searching for forces beyond the Standard Model

8th May 2018 – The ATLAS collaboration is continuing to scour the wealth of data provided by the LHC for any signs of physics beyond the particles and interactions described by the Standard Model. One approach is to search for new forces in addition to the Standard Model’s electroweak and strong interactions. Such forces could be propagated by new massive bosons playing the role the W and Z bosons have in mediating the electroweak force.

Charming SUSY: running out of places to hide

7th May 2018 – Why is gravity so much weaker than the other forces of nature? This fundamental discrepancy, known as the “hierarchy problem”, has long been a source of puzzlement. Since the discovery of a scalar particle, the Higgs boson, with a mass of 125 GeV near that of the W and Z bosons mediating the weak force, the hierarchy problem is more acute than ever.

ATLAS starts new year of data-taking

30th April 2018 – On 28 April, the ATLAS Experiment began recording the first data for physics of 2018. This will be the final year of Run 2 operation of the Large Hadron Collider and will mark the conclusion of the rich 13 TeV data harvest. Starting in 2019, the accelerator and its experiments will enter a long upgrade and maintenance period.

Hands-on particles: Schools worldwide analyse ATLAS data

23rd April 2018 – Every spring, hundreds of universities around the world open their doors to high-school students for a day to give them hands-on experience in particle physics. The International Masterclass programme gives students the chance to use real data collected by the ATLAS detector and other LHC experiments to test the Standard Model and search for new particles.

Beyond discovery: ATLAS explores the Higgs boson

11th April 2018 – The ATLAS Collaboration at CERN has released new studies of the Higgs boson using 13 TeV data collected in 2015 and 2016. The results further corroborate the Standard Model nature of the Higgs boson, and open doors to fresh searches for new physics.

ATLAS on track for 2018 data taking

30th March 2018 – It’s kick off at the Large Hadron Collider! Proton beams are circulating once again in the accelerator, marking the start of a new year of exploration for the ATLAS experiment.

Will.i.am and Roosevelt High School students

Angels and Teachers

27th March 2018 – I met beautiful people in Los Angeles earlier this month: smart, talented students, all destined for great careers. They welcomed me to their high schools and their after-school programmes, all well-equipped with computing, electronics, a robotics lab and, above all, a brilliant staff of teachers.
