Here we are. As of yesterday LHC is switched off: even the last high-intensity tests are over (collisions had already ended on Friday), and Run 3 is definitively finished. Tomorrow, early in the morning, on 29 June 2026, Long Shutdown 3 officially begins, and it will last until the restart in 2030. [1]That's what the official schedule says, but, as we know, of the morrow there is no certainty. There are […]

FrancoisEnglert, who invented, together with his colleague Robert Brout and in parallel with Peter Higgs, the mechanism of electroweak symmetry breaking that we commonly call the Higgs mechanism, or better, the Brout-Englert-Higgs mechanism, passed away a few days ago at the age of 93. Englert had shared with Peter Higgs the 2013 Nobel Prize […]

I code out of necessity, and I might finally be able to stop

Inmid-January I gave a public talk in Annecy where I was telling an audience of curious people how a Higgs boson is produced and its properties measured (and why, but that's another story). In the conversation with the audience that always follows these events, I received among others a question that comes up more and […]

Overthe past few months, despite my sporadic presence on these pages, I’ve been reporting in bits and pieces on the work done for the update of the European Strategy for Particle Physics. I had, for instance, written about it during the French symposium, which was expected to lead to the drafting of a national […]

We have beam in the tunnel!Today, the Large Hadron Collider received the first particle beams of 2025. Protons were injected into the LHC for the first time since November 2024, when the annual year-end technical stop (YETS) started. This is the fourth year of LHC Run3, and the new data-taking season is about to

(Thisis the English translation of this post)About a month ago, the Report on European Union Competitiveness, tasked to Mario Draghi by the European Commission, was released. It has been discussed widely, and I don't intend to provide a full analysis here. However, I find it interesting to highlight an aspect that I […]
