Abstract

Searches for the Higgs boson decays H → ee and H → eμ are performed using data corresponding to an integrated luminosity of 139 fb⁻¹ collected with the ATLAS detector in pp collisions at √s = 13 TeV at the LHC. No significant signals are observed, in agreement with the Standard Model expectation. For a Higgs boson mass of 125 GeV, the observed (expected) upper limit at the 95% confidence level on the branching fraction B(H → ee) is 3.6 × 10⁻⁴ (3.5 × 10⁻⁴) and on B(H → eμ) is 6.2 × 10⁻⁵ (5.9 × 10⁻⁵). These results represent improvements by factors of about five and six on the previous best limits on B(H → ee) and B(H → eμ) respectively.
