FCC Physics, Experiments and Detectors: from Strategy Update to Project Preparation
From detector concepts to future experiment collaborations, the FCC Physics, Experiments and Detectors programme is entering a new phase. Patrick Janot outlines how the Reference Design Phase will bring together physics ambitions, detector R&D and international collaboration to prepare FCC-ee for project approval and delivery.

FCC Week 2026: from scientific ambition to an integrated design
FCC Week 2026: from scientific ambition to an integrated design by Panos Charitos (CERN) This year’s annual conference brought together 656 participants in Helsinki to examine how the Future Circular Collider study can move from feasibility demonstration towards a coherent reference design. With its primary focus on FCC-ee, the meeting presented a project in which

In discussion with Alan Guth
Alan Guth reflects on the origins of inflationary cosmology, the uncertainty surrounding its earliest models and the observations that could shape its future. He also discusses eternal inflation, the measure problem and the enduring connections between cosmology and particle physics.

Looking for soft unclustered energy patterns from dark matter in CMS and ATLAS
CMS and ATLAS are exploring unconventional signatures of dark matter at the LHC. New searches target soft unclustered energy patterns—nearly spherical sprays of low-energy particles that can evade conventional detection strategies—and extend sensitivity to previously unexplored regions of the dark sector.

ANUBIS: from prototype to Letter of Intent
The proANUBIS demonstrator has completed data taking in the ATLAS cavern, showing that its detector technology delivers the efficiency and timing precision required to search for long-lived particles. These results strengthen the case for the full ANUBIS experiment, which would extend ATLAS’s reach into a largely unexplored region of new physics.

Past and Present of the LHC Physics Programme: A Viewpoint
Before the LHC began operations, expectations were immense. It was not perceived simply as CERN’s next machine after LEP, but as “the next machine after everything”—a collider expected to settle how electroweak symmetry is broken.

New Staff Members and Fellows – Autumn 2026
New Staff Members and Fellows – Autumn 2026 Christian Appelt Hello, I’m Christian. I’ve joined EP-ATL-SO as a Research Fellow. I completed professional training as an electronics technician, worked in industry for 5 years, and studied electrical engineering (BEng) and physics (BSc, MSc, PhD). I’ve worked at several research institutes; in ATLAS, I’ve been involved in and am leading long-lived particle searches, the production

Four of a kind: exploring quadruple-Higgs boson production at the HL-LHC
Four Higgs bosons from a single LHC collision would be a remarkable sight. The Standard Model puts an observation out of reach at the High-Luminosity LHC. Yet events containing four Higgs bosons could still matter for today’s experimental search strategies—and become much more abundant if new scalar particles exist.

Taking ATLAS apart to build its future
In the first weeks of Long Shutdown 3, ATLAS entered a decisive new phase. Over the next four years, the collaboration will dismantle major parts of the detector and install new tracking, timing, trigger and infrastructure systems for the High-Luminosity LHC. Its technical coordination team reveals the intricate planning, tension and unexpected joy behind this…

From beam dumps to missing energy: the SPS search for hidden particles
For more than four decades, CERN’s Super Proton Synchrotron has served as a testing ground for new ways to search for particles that interact only feebly with ordinary matter. In a recent lecture, NA64 co-spokesperson Paolo Crivelli traced the evolution of this programme – from the first beam-dump experiments to missing-energy and missing-momentum searches, precision…
