“…By the start of the LHC program the Tevatron experiments had excluded a Z boson mass lower than 700 GeV [102,103]. In the course of 2011 and 2012 the limit was extended to 800 GeV by a D0 search on nearly 5 fb −1 [105] and to approximately 900 GeV by a CDF analysis of the complete Tevatron data set [106]. An ATLAS search on 2.4 fb −1 of 7 TeV LHC data [107] collected in 2011 reached a similar precision.…”

This report of the BOOST2012 workshop presents the results of four working groups that studied key aspects of jet substructure. We discuss the potential of firstprinciple QCD calculations to yield a precise description of the substructure of jets and study the accuracy of state-ofthe-art Monte Carlo tools. Limitations of the experiments' ability to resolve substructure are evaluated, with a focus on the impact of additional (pile-up) proton proton collisions on jet substructure performance in future LHC operating scenarios. A final section summarizes the lessons learnt from jet substructure analyses in searches for new physics in the production of boosted top quarks.

“…Constraints on Z TC2 have been set by the CDF [23,24] and D0 [25] collaborations using data from proton-antiproton collisions at the Tevatron. Previous constraints at the LHC were set using proton-proton collisions at √ s = 7 TeV with an integrated luminosity of 5 fb −1 by the ATLAS [16,26] and CMS [27][28][29] collaborations, and using 20 fb −1 of √ s = 8 TeV data by the CMS Collaboration [18].…”

A search for new particles that decay into top quark pairs is reported. The search is performed with the ATLAS experiment at the LHC using an integrated luminosity of 20.3 fb −1 of proton-proton collision data collected at a centre-of-mass energy of √ s = 8 TeV. The lepton-plus-jets final state is used, where the top pair decays to W + bW −b , with one W boson decaying leptonically and the other hadronically. The invariant mass spectrum of top quark pairs is examined for local excesses or deficits that are inconsistent with the Standard Model predictions. No evidence for a top quark pair resonance is found, and 95% confidence-level limits on the production rate are determined for massive states in benchmark models. The upper limits on the cross-section times branching ratio of a narrow Z boson decaying to top pairs range from 4.2 pb to 0.03 pb for resonance masses from 0.4 TeV to 3.0 TeV. A narrow leptophobic topcolour Z boson with mass below 1.8 TeV is excluded. Upper limits are set on the cross-section times branching ratio for a broad colour-octet resonance with Γ/m = 15% decaying to tt. These range from 4.8 pb to 0.03 pb for masses from 0.4 TeV to 3.0 TeV. A Kaluza-Klein excitation of the gluon in a Randall-Sundrum model is excluded for masses below 2.2 TeV.

“…Particles and couplings predicted by extensions of the SM can affect the observed production cross sections of top quarks. For example, the observed top-quark pair (tt) production cross section in all of the experimental final states may be enhanced above the SM expectation by the production of new resonances [9,10], or the observed production cross section in some of the experimental final states may be altered from the SM expectation by top quark decay into new channels, such as a hypothesized charged Higgs boson and b quark [11,12].…”
