In this summary report of the 2001 Snowmass Electroweak Symmetry Breaking Working Group, the main candidates for theories of electroweak symmetry breaking are surveyed, and the criteria for distinguishing among the different approaches are discussed. The potential for observing electroweak symmetry breaking phenomena at the upgraded Tevatron and the LHC is described. We emphasize the importance of a high-luminosity $e^+e^-$ linear collider for precision measurements to clarify the underlying electroweak symmetry breaking dynamics. Finally, we note the possible roles of the $mu^+mu^-$ collider and VLHC for further elucidating the physics of electroweak symmetry breaking.

Report of the Higgs working group for the Workshop `Physics at TeV Colliders, Les Houches, France, 21 May - 1 June 2001. It contains 7 separate sections: A. Theoretical Developments B. Higgs Searches at the Tevatron C. Experimental Observation of an invisible Higgs Boson at LHC D. Search for the Standard Model Higgs Boson using Vector Boson Fusion at the LHC E. Study of the MSSM channel $A/H to tau tau$ at the LHC F. Searching for Higgs Bosons in $tbar t H$ Production G. Studies of Charged Higgs Boson Signals for the Tevatron and the LHC
The past few years have seen dramatic breakthroughs and spectacular and puzzling discoveries in astrophysics and cosmology. In many cases, the new observations can only be explained with the introduction of new fundamental physics. Here we summarize some of these recent advances. We then describe several problem in astrophysics and cosmology, ripe for major advances, whose resolution will likely require new physics.
We review theoretical and phenomenological aspects of heavy flavour production as discussed in the heavy flavour working group of the DIS 2012. Recent theoretical progress includes approximate NNLO calculations for heavy quark structure functions in deep inelastic scattering, the extension of the ACOT heavy flavour scheme to jet production, and advances in top physics where the highlight is clearly the first complete NNLO QCD prediction for top pair production in the $q bar{q}$ annihilation channel. Furthermore, state of the art phenomenological predictions for open charm and bottom, charmonium, and single top and top pair production are discussed in addition to other topics such as the effect of double parton scattering on heavy quark production. New measurements on charm and beauty production presented in the heavy flavor working group are summarized and discussed in comparison with QCD predictions. Top quark strong and weak couplings as well as top quark properties are being measured with precision at the LHC and the Tevatron. We summarize also recent results on spectroscopy of charmonia, bottomonia and $b$-hadrons, along with studies of their decays and properties. Searches for physics beyond Standard Model through precise measurements of rare decays of heavy flavours are discussed as well.
This report summarizes the work of the Energy Frontier Top Quark working group of the 2013 Community Summer Study (Snowmass).
A wide array of deep-inelastic-scattering and hadron collider experiments have tested the predictions of the electroweak theory and measured its parameters, while also searching for new particles and processes. We summarise recent measurements and searches that probe the Standard Model to unprecedented precision.
