Description

The focus of this meeting will be on the measurement of sin2thetaW, both on the theoretical side and on the experimental side (targeting a possible LHC combination in the future). There will also be other discussions following on from previous meetings (in particular concerning the measurement of mW) and more generally from existing and forthcoming precision measurements in the Drell-Yan sector.

      General discussion on interpretation of LHC observables in terms of s2w 1h 30m

      Not exhaustive list of topics:
      - Overall model dependence of interpretation: how does one step outside SM and how does one then compare to previous results (LEP)
      - EW scheme dependence of interpretation
      - Benchmarking of EW/QED effects in QCD environment
      - QCD dependence of interpretation: asymmetries versus cross sections
      - Benchmarking of tools to be used for future measurements and combinations

      Speaker: All
