llll->ZZ Reconstruction

Upon initial analysis of the samples, zero background was found, so various changes in the lepton cuts and pt cuts were used to create the following table.

This table represents the values of the Z1 mass integral for each channel with the lepton pt cut set at 5GeV, using different lepton quality cuts.

The different lepton quality cuts involved are reconstructing Z's using different ordering of Good and Any leptons, and also by allowing more "bad" leptons to see how much background is recovered.

The order of the values in each cell are: AnyAny? -AnyAny, GoodAny? -AnyAny, GoodAny? -GoodAny, GoodGood? -AnyAny, GoodGood? -GoodAny

The bolded values are GoodAny? -GoodAny, and GoodGood? -AnyAny respecitvely as they are the unintuitive values.
