NLO EW corrections for Sherpa ZZ -> llvv samples

Talks

* llvv meeting on 28 Cot 2019 EW corrections for ZZ (Sarah Heim): a talk that summarizes what we got from the theorists:

EW k-factors

EW k-factors. I would use d03-x01-y01 for now (Zvv pt, Zmass selection). The HM selection is in d05-x01-y01, you can see that the numbers are quite close but cut-off at 120 GeV.

• Average EW correction factors
• Corresponding absolute uncertainties on k-factors
• Plots for multiplicative and additive corrections

The k factors we use are the average, and the uncertainty band spreads over the difference.
