  1. 27. Feynman integrals in QFT
    JONATHAN RONCA
    17/04/2024 10:00
    Higgs and EW physics

    In this talk, I will review theoretical and phenomenological aspects of multi-loop amplitudes, focusing on the their wide range of physical applications. I will gently introduce the method employed in the calculation of the gg -> HH NLO SM and Beyond cross section to show where Feynman integrals enter, and where calculation bottleneck may arise.
    The increasing mathematical understanding of...

  2. 48. A Cosmological Solution to the Doublet-Triplet Splitting Problem
    Pablo Sesma (IPhT Saclay)
    17/04/2024 10:25

    We propose a model that can solve simultaneously the doublet-triplet splitting problem of grand unified theories, the electroweak hierarchy problem and the strong CP problem. The mechanism is based on the dynamics of two light scalars that can crunch the universe at the QCD phase transition if triplets are light or if the doublets are heavy or do not have a vev. The same mechanism was...

  3. 46. Electroweak W±Z production measurement at √𝑠=13 TeV with the ATLAS detector and an EFT interpretation.

  4. 31. Exploring Higgs Boson Properties: Insights from the ATLAS Group at LNF
    Chiara Arcangeletti (INFN-LNF)
    17/04/2024 11:45
    Higgs and EW physics

    Since the discovery of the Higgs boson, the ATLAS group at LNF has been studying its properties, particularly in the four-lepton decay channel. Known as the “golden channel,” this process played a crucial role in the discovery of the Higgs boson in 2012 and continues to be one of the primary final states for precise measurements of its properties, such as mass, spin/CP, and couplings with...

  5. 49. Top mass uncertainties in double Higgs production
    Giuseppe Degrassi (Universita' Roma Tre, INFN sez. Roma Tre)
    17/04/2024 12:10

    I will discuss the uncertainties due to the top-mass renormalization scheme allowing the trilinear Higgs boson self-coupling to vary around its Standard Model value including parton shower effects.

  6. 50. Higgs prospects at the FCC-ee

  7. 47. Probabilistic theory uncertainties from missing higher orders
    Marco Bonvini (INFN Roma)

    I present a probabilistically founded definition of theory uncertainties in perturbative computations due to the unknown higher orders. I show its performance against canonical recipes such as scale variation. I finally discuss future directions.
