Descripción
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 3.4 σ (2.5 σ 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.
