  1. 9. Keynote talk 2: Higgs sector - a perspective
    Kostas Nikolopoulos (University of Birmingham)
    25/06/2020, 15:45

    Significant progress has been made in the study of the Higgs boson in the last few years, and in the search of additional scalars. The large datasets already collected by the Large Hadron Collider experiments allow for ever more precise measurements, while the development of innovative tools and novel theoretical ideas open new windows in the exploration of the Higgs sector. Highlights of the...

  2. 51. Search for CP-odd ttH production in the H->bb decay channel with ATLAS
    Ana Luisa Carvalho (LIP)

    PhD student talk

    Following the observation of associated production of a Higgs boson with a pair of top-anti-top quarks (ttH), it is now essential to explore the detailed properties of the Higgs-Top coupling to test the predictions of the Standard Model of Particle Physics and search for clues of new physics that can modify this interaction. This talk describes the search to constrain odd charge-parity (CP)...

  3. 44. Probing the CP nature of the top-Higgs coupling in ATLAS
    Emanuel Gouveia (LIP)

    PhD student talk

    The observation of the Higgs boson production in association with a top quark pair (ttH) by ATLAS and CMS in 2018 directly confirmed the existence of the top quark Yukawa coupling. The Standard Model (SM) predicts a CP-even structure to this coupling, but a CP-odd component can arise in models beyond the SM (BSM). Recently, ATLAS and CMS searched for such a component in analyses targetting ttH...

  4. 52. Study of the Spin/CP properties of the Higgs coupling to W bosons with ATLAS at the LHC
    Ricardo Barrué (LIP)
    25/06/2020, 17:00
    PhD student talk

    In my presentation, I will motivate the use of angular observables as a probe of anomalous Spin/CP components in the HWW interaction vertex. I will present the results of the first ATLAS search of associated WH production in the boosted regime, where the sensitivity to these components is higher. I will also motivate and present some of my work as part of the ATLAS jet trigger group.
