ATLAS moves into top gear for Run 3

The ATLAS Collaboration has just released its first Run 3 measurements, studying data collected in the first half of August 2022. Researchers have measured the interaction strength (or cross-section) of two well-known processes: the production of a pair of top quarks and the production of a Z boson.

ATLAS Experiment records “first physics” at new high-energy frontier

“We have proton collisions in the ATLAS experiment.” At 16.47 CEST, the Large Hadron Collider (LHC) officially kicked off its third period of operation (Run 3). The LHC is colliding proton beams at a world-record-breaking energy of 13.6 tera electron volts (TeV). The higher beam energy and intensity of Run 3 will allow the ATLAS experiment to push the very limits of its physics research.

ATLAS Pixel detector readies to tackle Run 3

The ATLAS experiment at the Large Hadron Collider (LHC) is on the eve of a new data harvest with the restart of the LHC for Run 3. The upcoming four-year run will provide a dataset nearly twice the size of what was collected in Run 2 (2015–2018).

Countdown to physics: Beams splash in the ATLAS experiment

After over three years of upgrade and maintenance work, proton beams are back in the Large Hadron Collider! Friday 22 April 2022 marked the start of the LHC’s third operation period (Run 3), which will see a record number of collisions in the ATLAS detector.
