    Dr Maria Moreno Llacer (Univ. of Valencia and CSIC (ES))
    4/15/20, 9:30 AM

    The top Yukawa coupling can be probed using different physics process at the LHC (ttH, tH, 4-tops, etc.). The latest results on this together with global interpretations with other top (or Higgs) processes will be presented.

  8. 7. Constraining the Higgs-gauge couplings through differential SMEFT analyses
    Shankha Banerjee (University of Durham (GB))
    4/15/20, 2:30 PM

    In this talk, I will focus on the measurements of the Higgs couplings to the electroweak bosons, in the context of an effective field theory. I will also discuss the possibility of strongly constraining the couplings affecting the charged triple gauge boson vertices upon studying the Zh and Wh channels in the boosted Higgs regime. Finally, I will discuss the prospects of disentangling the...

  10. 9. The dimension-8 SMEFT for Higgs and electroweak physics
    Sandeepan Gupta (IPPP, Durham University)
    4/15/20, 3:30 PM

    In this talk I will discuss how dimension 8 effects can be systematically studied in Higgs and electroweak physics. After presenting a full list of dimension 8 operators that correct these processes, we will discuss how they connect to observables. The effects from these operators can be classified into two categories, (1) those arising from new contributions to vertex structures already...

  11. 12. The Geometric SMEFT
    Adam Martin (Fermilab)
    4/15/20, 4:30 PM
  12. 11. Ward Identities for the Standard Model Effective Field Theory
    Andreas Helset (Niels Bohr Institute)
    4/15/20, 5:00 PM

    We derive Ward identities for the standard model effective field theory using the background-field method. The resulting symmetry constraints on the standard model effective field theory are basis independent, and constrain the perturbative and power-counting expansions. A geometric description of the field connections, and real representations for the SU(2)L×U(1)Y generators, underlies the derivation.

    Manuel Maria Perez-Victoria Moreno De Barreda (Universidad de Granada (ES))

  15. 16. The Higgs EFT is a black hole
    Dave Sutherland
    4/16/20, 10:00 AM

    We consider the question of whether the scalar sector of the Standard Model, and possible deviations from its predicted interactions, are best parametrised by "SMEFT" or "HEFT". Here "SMEFT" means an effective field theory built out of a Higgs doublet, whose components transform linearly under electroweak symmetries; "HEFT" is built out of a singlet Higgs field and three Goldstones upon which...

    4/16/20, 10:30 AM

    I will present new results about the UOLEA which now allow to consider EFTs for which heavy fermions (vector like and chiral) have been integrated out.

  21. 22. Charm Physics Confronts High-pT Lepton Tails
    Javier Fuentes-Martin (University of Zurich)
    4/16/20, 3:00 PM

    I present a phenomenological investigation of possible short-distance new physics in (semi)leptonic charmed-meson decays. Using the Standard Model effective field theory, we demonstrate the complementarity with the production of high-pT leptons at the LHC. Our combined analysis of the latest low- and high-energy experimental data shows that much of the room for new physics in charm decays is...

  29. 30. High-energy constraints from low-energy neutrino non-standard interactions
    Jorge Terol Calvo (IFIC (CSIC-Univ València))
    4/17/20, 10:30 AM

    Many scenarios of new physics predict the existence of neutrino Non-Standard Interactions, new vector contact interactions between neutrinos and first generation fermions beyond the Standard Model. In this talk we will present model-independent constraints on the Standard Model Effective Field Theory at high energies from bounds on neutrino non-standard interactions derived at low energies....

  31. 32. Correlating uncertainties within the SMEFT
    Stefan Bißmann
    4/17/20, 12:00 PM

    We investigate the impact of correlations between (theoretical and experimental) uncertainties on multi-experiment, multi-observable analyses within the Standard Model Effective Field Theory (SMEFT). To do so, we perform a model-independent analysis of t-channel single top-quark production and top-quark decay data from ATLAS, CMS, CDF and D0. We show quantitatively how the fit changes when...

  32. 33. Precision constraints on non-standard EW/Higgs couplings with HEPfit
    Jorge de Blas (University of New Hampshire (US))
    4/17/20, 12:30 PM

    In this talk I present the HEPfit code, a flexible open-source tool to perform statistical tests of the Standard Model or any of its extensions. I will focus the talk on the current capabilities of the code for studies of the electroweak and Higgs sectors. As an example of such capabilities, we consider the case of physics beyond the SM parameterized by the dimension-6 SMEFT, and derive bounds...
