Measurement of inclusive and differential cross sections in the H → Z Z ∗ → 4 ℓ decay channel in p p collisions at s = 13 TeV with the ATLAS detector

CERN-LHC. Measurements of fiducial and differential cross sections of Higgs boson production in the H->ZZ*->4l channel in proton-proton collisions at a centre-of-mass energy of 13 TeV with 36.1 fb^-1 of data collected in 2015 and 2016. The final states used are 4 electrons, 4 muons, 2 electrons and 2 muons.

Search for new phenomena in events with missing transverse momentum and a Higgs boson decaying into two photons at s = 13 TeV with the ATLAS detector

CERN-LHC. A search for dark matter in association with a Higgs boson decaying to two photons. The final state is two photon plus missing transverse energy. The photons are defined with pT threshold of 0.35*m_yy and 0.25*m_yy for the leading and subleading photon, with the pseudo-rapidity |eta|<2.37. The events are categorized into mono-Higgs, high MET, intermediate MET categories. The mono-Higgs category requires the MET significance, defined by MET/sqrt(sumEt), to be greater than 7 and the diphoton pT larger than 90 GeV. The high MET category is MET significance greater than 5.5 and the intermediate MET category is MET significance greater than 4. Each category exclude the previous higher category. 1 unit of the MET significance is roughtly 20 GeV.
