Le boson de Higgs et sa place dans le modèle standard

d) Distribution of the acoplanarity angle, all other cuts being applied, for the data (trian- gles with error bars) and the Monte Carlo (shadowed histogram). The full line results

The largest contri- butions are due to the limited Monte Carlo statistics and to uncertainties on the background modelling, the W-pair cross section and the lepton

For values Ψ fit varied during the fitting procedure, the Ψ-dependent total and differential signal and background cross sections are determined by a reweighting procedure applied

After applying cuts on the neural networks, the analyses produce final distributions of the selected signal, background, and data, generally using a discriminant combination of

In 2012 the Large Hadron Collider (LHC), a circular particle collider located beneath the France-Switzerland border, publicly announced the discovery of a new particle with

Viewed in a simplified way, the analysis leading to the discovery of a new particle starts with the acquisition of experimental data; then a classifier is used to determine

In conclusion, theoretical arguments and experimental evidence ensure that no particles of the standard model are fakeons, apart from possibly the Higgs boson and the top quark,
