Systematics Breakdown • Generally compatible with note. • Electron momentum smearing uncertainty now an order of magnitude smaller, and decreases yields in both directions. • IP resolution seems slightly larger in the electron channel now. From Note New Systematics, ZZ selection only Nick Edwards
Binned Systematics breakdown - Electrons • Electron smearing behaves very oddly. • Electron energy scale increases significantly in higher bins. Compensated by drop in ID efficiency uncertainty 4e Nick Edwards
Binned Systematics breakdown - Muons • Again, smearing behaves quite oddly. Nick Edwards
