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

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.

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

The NNLO frontier
The NNLO frontier The potential of a post-LHC collider to explore for hints of new physics relies on technological advancements but also on theoretical developments that will allow very accurate background determinations. With a concensus growing for a lepton collider offering a wide range of precision Higgs and electroweak measurements it is important to consider

Interview with James Peebles
Interview with James Peebles An interview with Jim Peebles, one of the world’s foremost cosmologists and an emeritus professor at Princeton University, where since 1984 he was the Albert Einstein Professor of Science. Together with Robert Dicke (who was originally his supervisor) and others they predicted the existence of the cosmic background radiation while his
