Searches for invisible decays of the Higgs boson in pp collisions at √s = 7, 8, and 13 TeV
Searches for invisible decays of the Higgs boson are presented. The data collected with the CMS detector at the LHC correspond to integrated luminosities of 5.1, 19.7, and 2.3 fb−1 at centre-of-mass energies of 7, 8, and 13 TeV, respectively. The search channels target Higgs boson production via...

| Summary: | Searches for invisible decays of the Higgs boson are presented. The data
collected with the CMS detector at the LHC correspond to integrated luminosities of
5.1, 19.7, and 2.3 fb−1 at centre-of-mass energies of 7, 8, and 13 TeV, respectively. The
search channels target Higgs boson production via gluon fusion, vector boson fusion, and
in association with a vector boson. Upper limits are placed on the branching fraction of
the Higgs boson decay to invisible particles, as a function of the assumed production cross
sections. The combination of all channels, assuming standard model production, yields an
observed (expected) upper limit on the invisible branching fraction of 0.24 (0.23) at the
95% confidence level. The results are also interpreted in the context of Higgs-portal dark
matter models. |
