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

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.

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…

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

New pathways in axion searches
New pathways in axion searches Peering through telescopes we have found a deluge of evidence for dark matter. Given the speed that galaxies rotate, as well as theoretical calculations about the evolution of large-scale structure in the Universe, dark matter should make up 85% of the matter in the Universe. Despite considerable evidence in support

MADMAX prototype test at CERN
MADMAX prototype test at CERN Axion : A promising Dark Matter candidate For decades astronomical observations have indicated the existence of large quantities of dark matter in the universe. Until today, the nature of dark matter has not been understood and is therefore a central question in fundamental physics. The axion is among to the

Searching for axions: old and new ideas
Searching for axions: old and new ideas QCD, the theory of strong interactions allows the violation of CP symmetry that would result in a non-zero value for the neutron electric dipole moment. Current measurements constrain the neutron EDM to be one trillionth of the size predicted by QCD (because of CP violation). This means that
