| Searches for invisible Higgs boson decays with the CMS detector | ||

| July 2016 | ||
| Abstract: 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 cross sections, yields an observed (expected) upper limit on the invisible branching fraction of 0.24 (0.23) at a 95% confidence level. The results are also interpreted under Higgs-portal dark matter models. | ||

| Summary |
| A combination of searches for a Higgs boson decaying to invisible particles using Run 1 and Run 2 data sets has been presented. The combination includes searches targeting Higgs production in the ZH mode, in which a Z boson decays to $\ell^{+}\ell^{-}$ or $\mathrm{b\bar{b}}$, and the qqH mode which is the most sensitive channel. The combination also includes the first searches at CMS targeting VH production, in which the vector boson decays hadronically, and the ggH mode in which the Higgs boson is produced in association with jets. No significant deviations from the SM predctions are observed and upper limits are placed on the branching fraction for the Higgs boson decay to invisible particles. The combination of all searches yields an observed (expected) upper limit on $\mathrm{B}(\mathrm{H\rightarrow inv.)}$ of 0.24 (0.23) at a 95% confidence level, assuming SM production of a Higgs boson with the mass of 125 GeV. The combined 90% CL limit of $\mathrm{B}(\mathrm{H\rightarrow inv.)}< $ 0.20 has been interpreted in Higgs-portal models and constraints are placed on the spin-independent DM-nucleon interaction cross section. These limits provide stronger constraints than those from direct detection experiments for DM masses below 30 or 5 GeV, assuming a fermion or scalar DM particle, respectively. |
