abstract
This Report summarizes the results of the activities in 2012 and the first half of 2013 of the LHC Higgs Cross Section Working Group. 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. This report follows the first working group report Handbook of LHC Higgs Cross Sections: 1. Inclusive Observables (CERN-2011-002) and the second working group report Handbook of LHC Higgs Cross Sections: 2. Differential Distributions (CERN-2012-002). After the discovery of a Higgs boson at the LHC in mid-2012 this report focuses on refined prediction of Standard Model (SM) Higgs phenomenology around the experimentally observed value of 125-126 GeV, refined predictions for heavy SM-like Higgs bosons as well as predictions in the Minimal Supersymmetric Standard Model and first steps to go beyond these models. The other main focus is on the extraction of the characteristics and properties of the newly discovered particle such as couplings to SM particles, spin and CP-quantum numbers etc.

Explores q² dependence and imaginary parts of tau g-2 and EDM in SMEFT and 2HDM, proposing methods to measure them at Belle II and STCF to improve a_τ bounds by over an order of magnitude.
The paper supplies a unified framework and explicit translation dictionaries among the Higgs basis, κ's and angles, CP fractions, SMEFT, and Higgs EFT for describing CP-violating Higgs interactions.
Higgs boson cross-section in H→4ℓ measured as 3.65 fb with new LHC data, consistent with SM expectation of 3.68 fb and signal strength 0.99±0.13.
Combined differential and total Higgs boson production cross sections at 13 TeV are measured and found consistent with Standard Model expectations, with a total cross section of 53.4 pb.
In the 331ALP model the second Higgs is predicted above 600 GeV and the Z' above 5.1 TeV, with dark matter mass related to the axion breaking scale under a residual Z2 symmetry.
A review summarizing current observational, experimental, and theoretical results on dark matter.
Monte Carlo simulations of the diphoton Higgs channel in an effective coupling model reproduce the official ATLAS and CMS constraints on the gluon coupling modifier kappa_g.
