ATLAS plays a central role in the LHC's research by allowing physicists to test theoretical predictions in particle physics, including the existence of predicted but undiscovered particles, and to explore the fundamental forces and materials that shape our universe.

Jul 18, 2024 · The ATLAS Experiment at CERN has made two years’ worth of scientific data available to the public for research purposes. The data include recordings of proton–proton collisions from the Large Hadron Collider (LHC) at a collision energy of 13 TeV.

Jun 3, 2024 · Key results will be explored in ATLAS Physics Briefings, to be released throughout the conference. Check the LHCP 2024 tag for the latest updates. The full list of new ATLAS results presented at LHCP 2024 is given below and will be continually updated this week.

Feb 29, 2008 · We physicists refer to the vast underground cavern that houses the ATLAS experiment as ‘the pit’. That may be a strange term to use for a marvel of civil, mechanical and electrical engineering, but nonetheless there are parallels to what you might imagine a ‘pit’ to be.

Nov 25, 2024 · ATLAS physicists measured the B0 meson lifetime to be τ = 1.5053 ± 0.0012 (stat.) ± 0.0035 (syst.) ps. This result significantly improves upon previous lifetime measurements, including those from ATLAS and other experiments (see Figure 1).

Jan 18, 2023 · (Image: ATLAS Collaboration/CERN) Rising to the challenge To cope with the increased number of interactions when proton bunches collide at the HL-LHC, the ATLAS collaboration is working hard to upgrade its detectors with state-of …

The ATLAS detector weighs 7,000 tonnes, similar to the weight of the Eiffel Tower. The detector itself is a many-layered instrument designed to detect some of the tiniest yet most energetic particles ever created on earth.

Sep 18, 2024 · The ATLAS and CMS teams observed quantum entanglement between a top quark and its antimatter counterpart. The observations are based on a recently proposed method to use pairs of top quarks produced at the LHC as a new system to study entanglement.

Jul 21, 2023 · ATLAS sets record precision on Higgs boson’s mass, CERN Media Update, 21 July 2023 Measurement of the Higgs boson mass with H→γγ decays in 140 fb –1 of 13 TeV proton–proton collisions with the ATLAS detector (ATLAS-CONF-2023-036)
