It is therefore an extraordinary discovery tool that calls for a broad experimental programme at the LHC and beyond.”įabiola Gianotti CERN Director-General. “The Higgs boson is linked to profound structural problems in the Standard Model. The LHC Run 3 starts tomorrow: ready for the next decade of Higgs-boson exploration!”Īdinda de Wit CMS experimentalist (University of Zurich). “We have learned much about the 125 GeV Higgs boson since its discovery. Marco Delmastro ATLAS experimentalist (CNRS/IN2P3 LAPP). CP structure: in accordance with SM CP-even hypotheses.” Width: closing in on SM value of 3.2 +2.5 –1.7 MeV (plus evidence of off-shell Higgs production).

Kerstin Tackmann ATLAS experimentalist (DESY). “After 10 years we’ve measured the five main production and five major decay mechanisms of the Higgs boson.” Massimiliano Grazzini theorist (University of Zurich). Credit: CERN “Theory accuracy will be even more important to make the best of the HL-LHC data, especially in the case in which no evidence of new physics will show up… This is also crucial for the Monte Carlo tools used in the analyses.” “Precision Higgs physics is a telescope to high-scale physics, so I’m looking forward to the next 10 years of discovery.” Reisaburo Tanaka ATLAS experimentalist (Université Paris-Saclay). “Collaboration between experiment and theory is even more necessary now to find any hints for BSM physics.” To probe this phenomenon at the LHC we can study the production of Higgs-boson pairs.”Īndré David CMS experimentalist (CERN). “The structure of the vacuum is intimately connected to how the Higgs boson interacts with itself. Credit: CERN “The gist of the theory behind the Higgs boson would easily compete with the most far-fetched conspiracy theory, yet it seems nature chose it.”Įliezer Rabinovici president of the CERN Council. I would also like to celebrate the life of Robert Brout, a great physicist and important man.”įrançois Englert winner of the 2013 Nobel Prize in Physics. “I remember on 4 July 2012 a magnificent presentation of a historical discovery. Michel Della Negra founding CMS spokesperson. “A key question for CMS was: can tracking be done in a congested environment with just a few points, albeit precise ones? It was a huge achievement requiring more than 200 m 2 of active silicon.” “The first two years of measuring Standard Model physics were essential to give us confidence in the readiness of the two experiments to search for new physics.” At one point we had 1000 dipoles, each costing a million Swiss francs, stored on the surface, throughout rain and snow.” I especially remember the excitement among the young researchers.” It took time to understand what had happened. Credit: CERN “It was an overwhelming time for us. Peter Higgs winner of the 2013 Nobel Prize in Physics. I wish you well for your celebrations and regret that I can’t be with you in person.” Weinberg and I were working along similar lines with similar attitudes. “I am an opportunist, in one way an extremely successful one. For those who were unable to be there, the Courier provides a bite-sized digest. The symposium marking the 10th anniversary of the Higgs-boson discovery was a veritable Higgs feast that immersed participants in the history of the discovery, the latest results from ATLAS and CMS in understanding the Higgs-boson’s properties and interactions, and the potential of future precision measurements at the LHC and beyond. Many hundreds more connected remotely, while similar celebrations were held around the globe. Precisely 10 years later, with somewhat shorter queues, around 500 people packed into the same room to celebrate this momentous event in the history of particle physics. On the morning of 4 July 2012, Joe Incandela for CMS and Fabiola Gianotti for ATLAS presented results confirming the observation of a new elementary particle.
