  This Report summarizes the results of the activities of the LHC Higgs Cross
Section Working Group in the period 2014-2016. The main goal of the working
group was to present the state-of-the-art of Higgs physics at the LHC,
integrating all new results that have appeared in the last few years. The first
part compiles the most up-to-date predictions of Higgs boson production cross
sections and decay branching ratios, parton distribution functions, and
off-shell Higgs boson production and interference effects. The second part
discusses the recent progress in Higgs effective field theory predictions,
followed by the third part on pseudo-observables, simplified template cross
section and fiducial cross section measurements, which give the baseline
framework for Higgs boson property measurements. The fourth part deals with the
beyond the Standard Model predictions of various benchmark scenarios of Minimal
Supersymmetric Standard Model, extended scalar sector, Next-to-Minimal
Supersymmetric Standard Model and exotic Higgs boson decays. This report
follows three previous working-group reports: Handbook of LHC Higgs Cross
Sections: 1. Inclusive Observables (CERN-2011-002), Handbook of LHC Higgs Cross
Sections: 2. Differential Distributions (CERN-2012-002), and Handbook of LHC
Higgs Cross Sections: 3. Higgs properties (CERN-2013-004). The current report
serves as the baseline reference for Higgs physics in LHC Run 2 and beyond.
