Evidence for the Dimuon Decay of the Higgs Boson in pp Collisions with the ATLAS Detector
Author
Summary, in English
A search for the dimuon decay of the Higgs boson is presented based on pp collision data recorded by ATLAS during Run 3 of the Large Hadron Collider, corresponding to an integrated luminosity of 165 fb-1 at √s = 13.6 TeV. To enhance the sensitivity, the results are combined with those from Run 2. An excess of events over the background is observed with a significance of 3.4σ (2.5σ expected). The best-fit signal strength is μ = 1.4 ± 0.4. This result provides evidence for the H → μμ decay with ATLAS data and offers a direct probe of the Higgs-boson Yukawa coupling to second-generation fermions. © 2025 CERN, for the ATLAS Collaboration.
