Abstract

A search for the dimuon decay of the Higgs boson is presented based on 𝑝⁢𝑝 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→𝜇⁢𝜇 decay with ATLAS data and offers a direct probe of the Higgs-boson Yukawa coupling to second-generation fermions.
