Edge SpAIce: Leveraging CERN's AI for Real-Time Ocean Plastic Tracking from Space
Earth Observation (EO) and particle physics research have more in common than you might think. In both environments, whether capturing fleeting particle collisions or detecting transient traces of ocean plastics, rapid and accurate data analysis is…

Extending ATLAS Physics Reach with Analysis Reuse Technology
In August 2023, the ATLAS Collaboration presented the most comprehensive results to date of searches for electroweak production of supersymmetric particles interpreted within the Phenomenological Minimal Supersymmetric Standard Model (pMSSM)…

The ATLAS New Small Wheel - Triggering on muons and rejecting fakes
The New Small Wheel (NSW) [1] has been the largest Phase-1 upgrade project of ATLAS. The two innermost stations of the Endcap Muon spectrometer have been replaced with two newly built detector systems based on small-strip Thin Gap Chambers (sTGC)…

First analysis of Run 3 data with a new slim data format
The ATLAS Collaboration has just released a new measurement of the production cross-section of two Z bosons. This result examines data collected during Run 3 of the LHC – with protons colliding at a record energy of 13.6 TeV – and pioneers the use…

ATLAS and CMS unite to weigh in on the top quark
The ATLAS and CMS Experiments at CERN have just released a new measurement of the mass of the top quark. The new result combines 15 previous measurements to give the most precise determination of the top-quark mass to date. Among the known…

Ending the 2023 LHC run with heavy-ion collisions
The LHC schedule for 2023 has been revised following the emergence of a leak in mid-July. The decision was to stop the regular proton running this year and focus on the heavy ion physics that was already scheduled for the year-end. This was…

Triggering in ATLAS in Run 3
The ATLAS collaboration recently celebrated its 30th anniversary following the submission of the experiment’s Letter of Intent in 1992 and has accomplished great achievements during these years. However, it is still a young experiment, with only 6%…

A word from the DIRAC and Rucio Workshop 2023
DIRAC and Rucio are two software projects used for scientific computing. Both projects are led by CERN, and the EP department is one of the major contributors to both. DIRAC is used by CERN experiments such as LHCb, CLIC, FCC, NA62, and non-…

Jet Substructure as a powerful probe of Quantum Chromodynamics
Jet substructure (JSS) has emerged as a powerful framework for studying the Standard Model (SM) and provides a key set of tools for probing nature at the highest energy scales accessible by terrestrial experiments. While not an…
