The talk will discuss the challenges in top physics and theory bottlenecks to achieve high precision measurements.
Measurements of the top quark mass obtained by the ATLAS and CMS experiments in proton-proton collisions at the LHC for centre-of-mass energies of 7, 8 and 13 TeV are presented. The mass of the top quark is measured using several methods and channels, including the reconstructed invariant mass distribution of the top quark and shapes of kinematic observables from top quark decay products....
This presentation will cover recent results in the top quark sector from the CDF and DZero experiments in proton-antiproton collisions at a centre-of-mass energy of 1.96 TeV at the Tevatron. The topics include the final combinations of the forward-backward production asymmetry and of the top quark mass, as well as a limited selection of individual results.
Measurements and searches are presented of association top production processes (ttV and tV) in pp collisions at sqrt(s) = 13 TeV recorded by CMS and ATLAS. ttW is measured in the two same-sign lepton channel, obtaining an expected (observed) significance of 4.5 (5.3) standard deviations in the CMS analysis and (3.4) 3.9 in the ATLAS analysis. ttZ associated production is measured in the...
We report on the status of the precision measurements of electroweak parameters at CMS. The effective weak mixing angle sin^{2}_{\theta} is extracted by measuring the forward-backward asymmetry in di-lepton events near the Z boson mass region. The first observation of electroweak production of same-sign W boson pairs in proton-proton collisions is also reported.
I will summarize Tevatron electroweak measurements, with a focus on the recent D0 and CDF combination of the forward-backward asymmetry of leptons from Z boson production and decay. I will also touch on the latest and ongoing measurements of the W boson mass and of the charge asymmetry in its leptonic decays.
This talk will cover the latest results of the ATLAS collaboration concerning Electroweak precision measurements.
We present an update of the global fit of the Standard Model electroweak sector to latest experimental results. We include new top quark and W boson mass measurements from the LHC, a measurement of the weak mixing angle from the Tevatron, and a new evaluation of the hadronic contribution to the electromagnetic coupling. The electroweak data combined with measurements of the Higgs boson...
