Summary of the 95% confidence level observed limits on the effective field theory Wilson coefficients of the dimension-6 operators related to (top) quark interaction with vector bosons, as obtained by the ATLAS and CMS Collaborations. The results are reported as individual constraints assuming new physics contributions from one specific operator at a time. Interpretations use the SMEFT framework and the Warsaw basis. The formalism is employed at different levels of the experimental analyses, from the interpretation of measured observables to a comparison of the data to simulations at the detector level. Most interpretations follow the LHCtopWG recommendations from arXiv:1802.07237. In the measurement arXiv:2202.12134, the limit is derived for the coefficient CtG normalised with the strong coupling, gS, as implemented in SMEFT@NLO.

| W helicity combination at 8 TeV | http://arxiv.org/abs/2005.03799 |
 |
The combination of measurements of the W boson polarization in top quark decays performed by the ATLAS and CMS Collaborations is presented. The measurements are based on proton-proton collision data produced at the LHC at a centre-of-mass energy of 8 TeV, and corresponding to an integrated luminosity of about 20 fb-1 for each experiment. The measurements used events containing one lepton and having different jet multiplicities in the final state. The results are quoted as fractions of W bosons with longitudinal (F0), left-handed (FL), or right-handed (FR) polarizations. The resulting combined measurements of the polarization fractions are F0 = 0.693 +- 0.014 and FL = 0.315 +- 0.011. The fraction FR is calculated from the unitarity constraint to be FR = -0.008 +- 0.007. These results are in agreement with the standard model predictions at next-to-next-to-leading order in perturbative quantum chromodynamics and represent an improvement in precision of 25 (29)\% for F0 (FL) with respect to the most precise single measurement. A limit on anomalous right-handed vector (VR), and left- and right-handed tensor (gL, gR) tWb couplings is set while fixing all others to their standard model values. The allowed regions are [-0.11,0.16] for VR, [-0.08, 0.05] for gL, and [-0.04, 0.02] for gR, at 95\% confidence level. Limits on the corresponding Wilson coefficients are also derived.

| Charge Asymmetry at 7 and 8 TeV | http://arxiv.org/abs/1709.05327 |

This paper presents combinations of inclusive and differential measurements of the charge asymmetry (AC) in top quark pair (ttbar) events with a lepton+jets signature by the ATLAS and CMS Collaborations, using data from LHC proton-proton collisions at centre-of-mass energies of 7 and 8 TeV corresponding to integrated luminosities of about 5 and 20 fb-1 for each experiment, respectively. The resulting combined LHC measurements of the inclusive charge asymmetry are AC = 0.005 +- 0.007 (stat) +- 0.006 (syst) at 7 TeV and AC = 0.0055 +- 0.0023 (stat) +- 0.0025 (syst) at 8 TeV. These values, as well as the combination of AC measurements as a function of the invariant mass of the ttbar system at 8 TeV, are consistent with the respective standard model predictions.

This paper presents the combinations of single-top-quark production cross-section measurements by the ATLAS and CMS Collaborations, using data from LHC proton-proton collisions at sqrt(s)=7 and 8 TeV corresponding to integrated luminosities of 1.17 to 5.1 fb-1 at sqrt(s)=7 TeV, and 12.2 to 20.3 fb-1 at sqrt(s)=8 TeV. These combinations are performed per centre-of-mass energy and for each production mode: t-channel, tW, and s-channel. The combined t-channel cross-sections are 67.5 +- 5.7 pb and 87.7 +- 5.8 pb at sqrt(s)=7 and 8 TeV respectively. The combined tW cross-sections are 16.3 +- 5.7 pb and 23.1 +- 3.6 pb at sqrt(s)=7 and 8 TeV respectively. For the s-channel cross-section, the combination yields 4.9 +- 1.4 pb at sqrt(s)=8 TeV. The square of the magnitude of the CKM matrix element Vtb multiplied by a form factor fLVis determined for each production mode and centre-of-mass energy, using the ratio of the measured cross-section to its theoretical prediction. It is assumed that the top-quark-related CKM matrix elements obey the relation |Vtd|,|Vts| << |Vtb|. All the |fLV Vtb|2 determinations, extracted from individual ratios at sqrt(s)=7 and 8 TeV, are combined, resulting in |fLV Vtb|=1.02 +- 0.04 (meas.) +- 0.02 (theo.). All combined measurements are consistent with their corresponding Standard Model predictions. PNG February 2019 More Plots ATLAS link More Plots CMS link |
