The Higgs boson Turns Ten


Ten years ago, on July 4 2012, the ATLAS and CMS collaborations announced the discovery of a new particle consistent with the Higgs boson of the Standard Model (SM) of particle physics using the proton-proton collisions delivered by the Large Hadron Collider (LHC) at CERN.
The discovery marked a in the progress of particle physics due to the special role played by the Higgs boson in the SM theory of the microscopic phenomena [1].
 
Ten years later, a scientific symposium [2] is taking place at CERN [3] on July 4 2022, to celebrate the discovery, recollect the long but successful path that led to it, and take a look at the insight that was gained in the past decade about the Higgs boson. The latest new results by ATLAS [4,5,6] and CMS [7] include the latest constraints by ATLAS on the Higgs boson self-coupling that determines the shape of the Higgs field potential, and measurements of the Higgs boson couplings to the other SM elementary particles and the kinematic features of Higgs boson production. The ATLAS team of the APC laboratory has contributed significantly to both single-Higgs couplings [4] and differential cross-section [6] measurements, and to the most up-to-date and tight constraint on the Higgs boson self-interactions [5].
The celebrations will continue in the next days with a half-day celebration organised by IN2P3 on Wednesday July 6 2022 in Amphitheatre Buffon of Université Paris-Cité [8].
The results will also be presented with more details and discussions in the coming ICHEP 2022 conference [9].
 
Tuesday July 5 2022 will also mark the official start of the LHC Run 3 [10], at the unprecedented center-of-mass energy of 13.6 TeV. The increase in energy and in integrated luminosity with respect to Run 2 will lead to a Higgs boson sample which is almost twice as large as that of the previous runs, paving the way for an even more precise portrait of this fundamental particle.
