  1. 99. Jet Bundle Geometry of Scalar EFTs
    Mohammad Alminawi (University of Zurich (CH))

    Precision Higgs measurements and calculations

    Geometric formulations of scalar EFTs formulate fields as coordinates on a field space manifold, which provides an alternative method of studying theories by relating physical quantities emerging from the two derivative term to geometric tensors which are invariant under field redefinitions.

    Fibre bundles provide us with the tools to extend the formalism to both describe the potential via...

  2. 75. Examining the CP properties of the top-Yukawa and the ggH coupling

    BSM Higgs physics

    The $\mathcal{CP}$ structure of the Higgs couplings is a fundamental property which has not yet been constrained with high precision. The Higgs-top quark coupling is of particular interest due to its size and accessibility at the LHC via top-associated Higgs production and gluon fusion. To improve the sensitivity to the CP property of this coupling, we propose an extension to the STXS...

  3. 90. Single top plus Higgs at LHC with CP violating top Yukawa
    Ya-Juan Zheng

    BSM Higgs physics

    We study the single top plus Higgs production process at the LHC with a CP violating Yukawa coupling from a dimension-6 operator. The amplitude of the subprocess ub>dtH is obtained both in the Unitary (U) and Feynman-Diagram (FD) gauges. Energy and angular distributions of the cross section and CP violating asymmetries are understood clearly from the interference among the FD gauge amplitudes.
