Extended Scalar Sectors are considered from all angles at CERN
Extended Scalar Sectors are considered from all angles at CERN It has been more than ten years since the discovery of the first scalar particle at the electroweak scale. This particle was discovered at the LHC in 2012, and it was quickly found to be a scalar that is compatible with the Higgs boson predicted

LHC Run 3: A Marathon of Progress and Perseverance
LHC Run 3: A Marathon of Progress and Perseverance Earlier this month, the Large Hadron Collider reached an unprecedented milestone of 100 inverse femtobarns – equivalent to 10 million billion collisions – delivered to the ATLAS and CMS experiments in 2024, with 28 days of proton-proton collisions remaining. This marks a historic first in a

ATLAS Operations: Progress and Highlights from 2023/2024
ATLAS Operations: Progress and Highlights from 2023/2024 Great progress has been made in the ATLAS operation since the last EP news article. There we presented the fantastic Phase-I upgrades of the ATLAS detector installed during LS2, described the steps towards their commissioning, and summarized the experience of the first data-taking year of Run 3. What

A high-dimensional jet-powered measurement of the strong force
A high-dimensional jet-powered measurement of the strong force Top image: An event display of a high-momentum Z boson event in the ATLAS detector associated with a number of “jets”, which are complex clusters of particles created via interactions mediated by the strong force. Precise measurements of fundamental particles at the Large Hadron Collider (LHC) are

Edge SpAIce: Leveraging CERN’s AI for Real-Time Ocean Plastic Tracking from Space
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 paramount. We are excited to present a
