Abstract
Recent results on Higgs boson production and decays in the ATLAS and CMS experiments at the LHC are reviewed. They are mostly based on the analyses of 13 TeV LHC proton-proton collision data accumulated during 2015–2016 or 2015–2017 year exposures. Production cross sections in five main decay channels are measured. These channels are combined to extract the Higgs boson signal strength, mass and couplings. All experimental results are found to be compatible with the Standard Model predictions. Upper limits on non-standard Higgs boson production in different decay modes are also derived.
Highlights
The Large Hadron Collider (LHC) [1] at CERN provides proton-proton collisions at the center-of-mass energy of 13 TeV since 2015
Two huge multi-purpose experiments, ATLAS [2] and CMS [3] operate at the LHC
A brief summary of its expected production cross sections in different mechanisms as well as branching ratios (BR) is given in Section 2.1; in Section 2.2, the most sensitive bosonic decay modes, namely the h → ZZ → 4, h → γγ and h → W W → ν ν are considered; Section 2.3 is devoted to the fermionic decay modes h → τ τ and h → bb; in Section 2.4 the tth production is discussed
Summary
The Large Hadron Collider (LHC) [1] at CERN provides proton-proton (pp) collisions at the center-of-mass energy of 13 TeV since 2015. A new boson with a mass of 125 GeV, i.e. in-between the mentioned limits, was discovered by the ATLAS [6] and CMS [7] Collaborations at the Large Hadron Collider (LHC) six years ago.. A new boson with a mass of 125 GeV, i.e. in-between the mentioned limits, was discovered by the ATLAS [6] and CMS [7] Collaborations at the Large Hadron Collider (LHC) six years ago.2 This discovery was a great success of the SM as all measured properties of this particle were found to be compatible with the predictions for the h boson. A search for the SM Higgs boson at the LHC is a complicated task because the expected production cross section is σh = O(10) pb while the rate of background processes are much higher.
