Designing for the unusual: LLP2026 and the lifetime frontier
LLP2026 brought around 80 theorists and experimentalists to Cambridge at a moment of transition for the lifetime frontier. From new searches using Run 3 LHC data and unconventional signatures to prototype detectors and new experimental concepts, the workshop showed how long-recognised blind spots are being turned into concrete experimental capabilities.

New ATLAS and CMS searches narrow the gap for compressed higgsinos
New ATLAS and CMS searches narrow the gap for compressed higgsinos Supersymmetry plays a prominent role in the landscape of models that push beyond the Standard Model. Higgsinos, the supersymmetric partners of the Higgs boson, may help in addressing a number of unsolved puzzles, particularly if their masses are near the electroweak scale. Not only

In discussion with John Ellis: The Higgs, Patience and Perseverance in Science
In discussion with John Ellis: The Higgs, Patience and Perseverance in Science by Panos Charitos For John Ellis, the history of the Higgs boson is not a neat, short story that begins with a theory paper and ends with a discovery announcement. It is a long intellectual adventure, beginning in superconductivity, moving through the construction

ATLAS Turns Into a Precision Cosmic Ray Laboratory
ATLAS Turns Into a Precision Cosmic Ray Laboratory Event display of a proton-oxygen collision recorded in ATLAS Run 501640 on 1st July 2025 at 23:23:29 CEST. The event contains 19 reconstructed tracks (yellow lines) satisfying pT > 500 MeV with at least one Pixel hit and at least six SCT hits. Every second, roughly one

AI for Gravitational Waves: Building Bridges Between Scientific Communities
AI for Gravitational Waves: Building Bridges Between Scientific Communities As gravitational-wave observatories enter a new phase of sensitivity, scale and scientific ambition, the challenge is no longer only to detect faint ripples in spacetime. It is also to analyse, interpret and respond to them fast enough to open new windows on the Universe. This was

Rucio crosses the exabyte horizon
Rucio crosses the exabyte horizon When we last wrote in these pages about Rucio, ATLAS had just passed the half-exabyte mark and the community counted around thirty organisations. Six years on, a threshold that was then a distant projection has been crossed: both ATLAS and CMS, the two largest LHC experiments, now each manage more

Towards monitoring in Run 4 and beyond: LHC experiments exchange perspectives on data quality at the HL-LHC
Towards monitoring in Run 4 and beyond: LHC experiments exchange perspectives on data quality at the HL-LHC In March of 2026, experts from ALICE, ATLAS, CMS and LHCb gathered at CERN for a dedicated workshop on Data Quality Monitoring (DQM), bringing together developers, coordinators and detector specialists to discuss how the LHC experiments monitor the

FASER opens new windows on dark sectors and TeV neutrino physics
FASER opens new windows on dark sectors and TeV neutrino physics The FASER experiment has presented a series of new results that highlight the growing breadth of its physics programme at the LHC. These include a search for dark photons with the main FASER detector, a first search for neutrino-induced charm production with FASERν, and

ATLAS scales up AI for jet physics and reveals flavour-tagging scaling laws
ATLAS scales up AI for jet physics and reveals flavour-tagging scaling laws High Energy Physics (HEP) and Machine Learning (ML/AI) are uniquely aligned: The data recorded by particle physics experiments are so rich, heterogeneous and complicated that scientists crucially depend on advanced pattern recognition in order to extract physics results. It’s for this reason that
