This Report summarises the activities of the "SM and Higgs" working group for the Workshop "Physics at TeV Colliders", Les Houches, France, 2-20 May, 2005. On the one hand, we performed a variety of experimental and theoretical studies on standard candles (such as W, Z, and ttbar production), treating them either as proper signals of known physics, or as backgrounds to unknown physics; we also addressed issues relevant to those non-perturbative or semi-perturbative ingredients, such as Parton Density Functions and Underlying Events, whose understanding will be crucial for a proper simulation of the actual events taking place in the detectors. On the other hand, several channels for the production of the Higgs, or involving the Higgs, have been considered in some detail. The report is structured into four main parts. The first one deals with Standard Model physics, except the Higgs. A variety of arguments are treated here, from full simulation of processes constituting a background to Higgs production, to studies of uncertainties due to PDFs and to extrapolations of models for underlying events, from small-$x$ issues to electroweak corrections which may play a role in vector boson physics. The second part of the report treats Higgs physics from the point of view of the signal. In the third part, reviews are presented on the current status of multi-leg, next-to-leading order and of next-to-next-to-leading order QCD computations. Finally, the fourth part deals with the use of Monte Carlos for simulation of LHC physics.

Collider physics at the precision frontier (2020, methodology): “At the Les Houches 2005 Workshop at TeV Colliders, a realistic wish list was created, that contained 2→ 4 processes at NLO as the cutting edge [5].”
Dispelling the N3 myth for the kt jet-finder (2005, background): “Among its physics advantages are (a) that it purposely mimics a walk backwards through the QCD branching sequence, which means that reconstructed jets naturally collect most of the particles radiated from an original hard parton, giving better particle mass measurements [14, 15], general kinematic r”
Scalar and pseudoscalar Higgs production in association with a top–antitop pair (2011, background): “Several search strategies have been proposed, based on different decay modes: from bb̄ which leads to largest number of expected events, to the more rare but potentially cleaner ττ [5], WW (∗) [6] and γγ [7] final states.”
Fastjet:. Dispelling the N 3 Myth for the k t Jet-Finder (2007, background): “Among its physics advantages are (a) that it purposely mimics a walk backwards through the QCD branching sequence, which means that reconstructed jets naturally collect most of the particles radiated from an original hard parton, giving better particle mass measurements [14, 15], general kinematic r”
Towards jetography (2009, background): “Historically the approach taken to studying the quality of jet definitions has been to take hard partons in a Monte Carlo, let them shower and hadronise, and then see how closely the reconstructed hadron-level jets match the original partons (see for example [168]).”
Charged-particle multiplicities in pp interactionsmeasured with the ATLAS detector at the LHC (2010, background): “Charged-particle distributions are sensitive to multi-parton interactions (MPI) and CR of the hadronic final state [35]; the MPI are regulated by a low pT cut-off and the matter overlap distribution of the two protons in which the additional partonic scattering takes place.”
