  1. 738. Top-quark pair production cross-section measurements with the ATLAS detector
    Tom Neep (University of Birmingham (GB))
    06/05/2019, 16:30
    parallel talk

    Measurements of the inclusive and differential top-quark pair production cross sections in proton-proton collisions at a centre-of-mass energy of 13 TeV with the ATLAS detector at the Large Hadron Collider are presented. The investigated final states include ttbar+jets events, in particular ttbar+heavy flavour jets. The process of a ttbar pair produced in association with jets originating from...

  2. 670. Top quark pair property measurements using the ATLAS detector at the LHC

    parallel talk

    Precise measurements of the properties of the top quark test the Standard Model (SM) and can be used to constrain new physics models. The top-quark is predicted in the SM to decay almost exclusively into a W boson and a b-quark. We present a wide range of searches for non-SM top quark decays using the 13 TeV ATLAS datasets, including flavour-changing current processes t$\to$qH and t$\to$qZ. In...

  5. 752. Off-shell single-top-quark production in the Standard Model Effective Field Theory
    Tobias Neumann (Illinois Tech / Fermi National Accelerator Laboratory)
    06/05/2019, 17:30
    parallel talk

    We present a fully differential and spin-dependent t-channel single-top-quark calculation at next-to-leading order (NLO) in QCD including off-shell effects by using the complex mass scheme in the Standard Model (SM) and in the Standard Model Effective Field Theory (SMEFT). We include all relevant SMEFT operators at 1/Λ^2 that contribute at NLO in QCD for a fully consistent comparison to the SM...

  6. 773. Charming top decays with flavor changing Higgs boson and $\tau \tau$ at LHC
    Rishabh Jain (University Of Oklahoma)
    06/05/2019, 17:45
    parallel talk

    We study the prospect of discovering a rare $t \to c h^0$ decay in the top pair production channel at LHC. We follow a general two Higgs doublet model framework to investigate this signature, with Higgs decaying into $\tau \tau$ and another top decaying hadronically to a b quark and two light jets. We search for the following final states $b j j \ell^+ \ell^- + Missing Energy$ and $b j j...
