Fig. 4. (Color online) Distributions of an invariant mass (mee+) of an electron and a positron from: (a) Monte Carlo (MC) events of processes (red) (H1), (blue) (H2) and (black) (H3), (b) (red) reweighted MC events of (H1) by factor R12 to estimate a process (H2) Here MC samples are made using parton-level generator (Madgraph).
