Physicists confirm Higgs boson behaves as theory predicts
Scientists at the Large Hadron Collider have remeasured how often the Higgs boson is produced in particle collisions, finding results that match decades-old predictions with high precision. The finding validates the Standard Model of physics and strengthens confidence in the theoretical framework underlying particle physics research and industrial applications.
Originaltitel: Measurements of inclusive and differential Higgs boson production cross sections at √s = 13.6 TeV in the H → γγ decay channel
<p>Inclusive and differential cross sections for Higgs boson production in proton-proton collisions at a centre-of-mass energy of 13.6 TeV are measured using data collected with the CMS detector at the LHC in 2022, corresponding to an integrated luminosity of 34.7 fb−1. Events with the diphoton final state are selected, and the measured inclusive fiducial cross section is σfid = 74±11 (stat)+5−4(syst) fb, in agreement with the standard model prediction of 67.8 ± 3.8 fb. Differential cross sections are measured as functions of several observables: the Higgs boson transverse momentum and rapidity, the number of associated jets, and the transverse momentum of the leading jet in the event. Within the uncertainties, the differential cross sections agree with the standard model predictions.</p>
