Key4hep: A software framework for future collider studies
Key4hep brings future-collider communities together around a shared software framework for detector design and physics studies. By integrating tools for event generation, simulation, reconstruction and analysis, it reduces duplication, facilitates comparisons and allows each project to adapt the software to its own detector and scientific goals.

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

Light ions bring CMS closer to the onset of QGP-like behaviour
Light ions bring CMS closer to the onset of QGP-like behaviour What are the smallest droplets of strongly interacting matter that exhibit colour deconfinement? This question has become one of the most intriguing frontiers in heavy-ion physics. At very high temperatures and densities, quantum chromodynamics predicts that quarks and gluons are no longer confined inside

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

Out of the loop: CMS advances in the search for a rare Higgs boson decay
Out of the loop: CMS advances in the search for a rare Higgs boson decay Completing the Higgs boson’s profile requires probing some of its rarest decay modes. Among the few still awaiting observation is the decay into a Z boson and a photon (H → Zγ), which occurs in only about one out of
