Аннотация: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.
