Figure.2.a
Figures depicting the top-quark invariant mass reconstruction using the truth matching scheme for different levels of truth. As shown, a perfect peak around 172 GeV (truth-tops) is visible, with degrading resolution as more truth information is removed from the matching. The worst resolution is expected to be detector reconstructed jets and leptons.
