Resumen:
Combined measurements of Higgs boson production cross sections and branching fractions are presented using the H→γγ and H→ZZ∗→4ℓ decay channels, based on 36.1 fb−1 of proton?proton collision data recorded by the ATLAS experiment at the LHC at s√= 13 TeV. Results are presented for the individual production processes of gluon fusion, vector-boson fusion, WH, ZH, and tt¯H , and for kinematic subdivisions of these processes. The total cross section for pp→H+X is determined to be 57.0+6.0−5.9 (stat.) +4.0−3.3 (syst.) pb, consistent with the Standard Model prediction of 55.6+2.4−3.4 pb. The results are translated into constraints on coefficients of Standard Model couplings. No significant deviations from the expectations are observed.
