WebThe Higgs boson (H), discovered in 2012 by the ATLAS and CMS experiments, is the pinnacle of the scientific results obtained from the large hadron collider (LHC) at CERN. The properties of the Higgs boson are studied in minute detail by a large community of physicists using the data collected at the LHC. WebThe ATLAS detector, one of two experiments to spot the elusive Higgs boson in particle smashups at CERN’s Large Hadron Collider, weighs as much as a hundred 747 jets and …
The Higgs Boson Mystery: When Nature Defies Expectations
Web29 de jun. de 2024 · The Higgs boson discovery was announced by the ATLAS and CMS collaborations on 4 th July 2012. Evidence for a new particle with the mass of about 125 GeV and the properties of the Standard Model Higgs boson was present in the three decay modes H → ZZ* → ℓℓ ℓℓ, H → γγ, and H → WW* → ℓν ℓν in both experiments.

Higgs Boson Production at the LHC
Web21 de dez. de 2012 · On 4 July, researchers working with the world's biggest atom smasher—the Large Hadron Collider (LHC) in Switzerland—announced that they had spotted a particle that appears to be the long-sought Higgs boson, the last missing piece in physicists' standard model of fundamental particles and forces. Web4 de jul. de 2024 · The experimental determination of the couplings of the Higgs boson to each individual particle therefore provides important and independent tests of the standard model. It also provides stringent... Web27 de fev. de 2024 · LightGBM uses a leaf-wise algorithm instead and controls model complexity by num_leaves . So we cannot compare them in the exact same model setting. For the tradeoff, we use xgboost with max_depth=8, which will have max number leaves to 255, to compare with LightGBM with num_leaves=255.
