  1. 86. Measurements from Asacusa
    Dr Masaki Hori (Max Planck Institute for Quantum Optics)

    Experiment
    Ordinary
  2. 15. Determination of alpha(mZ) -- ALPHA collaboration
    Dr Alberto Ramos (CERN)

    Theory
    Ordinary
    We review the ALPHA collaboration strategy for obtaining the QCD coupling at the electroweak scale via Lattice QCD simulations. In the three-flavor effective theory we compute non-perturbatively the running of the strong coupling from hadronic scales to the electroweak scale. The result for the Lambda parameter in the three-flavor effective theory is used to obtain an accurate value of the...

  3. 50. EW precision data and the 1-loop Z decay width in the SM effective theory

    Theory
    Ordinary
    We discuss the interpretation of some electroweak precision data in the SMEFT. Constraints and results for partial one loop results for the Z decay width, and related observables, in the SMEFT are shown.

  4. 25. W mass measurement
    Dr Nansi Andari (Universite de Birmingham)
    20/03/2017 09:35
    Experiment
    Ordinary
    A first measurement of the W-boson mass at the LHC is presented based on about 4.6 fb^-1 of proton–proton collision data recorded in 2011 at a centre-of-mass energy of 7 TeV with the ATLAS detector. The measured value is 80370±19 MeV, consistent with the Standard Model prediction, with the combined values measured at the LEP and Tevatron colliders, and with the world average. The ATLAS result...

  5. 42. PDF determination and the W mass
    Prof. Stefano Forte (Dipartimento di Fisica, Università di Milano)
    20/03/2017 10:15
    Theory
    Ordinary
    I summarize the state of the art in the determination of parton distribution functions (PDFs). I specifically discuss the determination of the W mass as a test case for the study the impact of the knowledge of PDFs and their uncertainties on precision physics at the LHC. I present prospects of improvement thanks to LHC data in the coming years and I discuss the theoretical, experimental and...
