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 x 10(-4) (3.5 x 10(-4)) and on B(H -> e mu) is 6.2 x 10(-5) (5.9 x 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 -> e mu) respectively.eninfo:eu-repo/semantics/openAccessLeading Order QcdBroken SymmetriesStrahlungMassFusionLhcArticle2-s2.0-8507676705710.1016/j.physletb.2019.135148Q2WOS:000508018500038
