Combination of the W boson polarization measurements in top quark decays using ATLAS and CMS data at root s=8 TeV
(SPRINGER, 2020)
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 ...
Measurement of the top quark forward-backward production asymmetry and the anomalous chromoelectric and chromomagnetic moments in in pp collisions at root s=13 TeV
(SPRINGER, 2020)
The parton-level top quark (t) forward-backward asymmetry and the anomalous chromoelectric ((d) over cap (t)) and chromomagnetic ((mu) over capt) moments have been measured using LHC pp collisions at a center-of-mass energy ...

(SPRINGER, 2020)
Measurements of the cross section for the production of top quark pairs in association with a pair of jets from bottom quarks (sigma(t (t) over barb (b) over bar)) and in association with a pair of jets from quarks of any ...
Search for new physics in top quark production with additional leptons in proton-proton collisions at √s = 13 TeV using effective field theory
(Springer Science and Business Media Deutschland GmbH, 2021)
Events containing one or more top quarks produced with additional prompt leptons are used to search for new physics within the framework of an effective field theory (EFT). The data correspond to an integrated luminosity ...
Search for top squark pair production in a final state with two tau leptons in proton-proton collisions at root s=13 TeV
