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.
