Case A

Case B

Image updated for Rivet 3.0.1, 30/10/2019.

Note decrease in sensitivity at low masses. This is due to a bug in the isolation criteria for leptons applied in ATLAS_2012_I1203852. Bug was present in Rivet 2.7, fixed in 3.0

Case C

Image updated for Rivet 3.0.1, 30/10/2019.

Note decrease in sensitivity at low masses as for Case B

Case D

Image updated for Rivet 3.0.1, 31/10/2019.

Case E

See [72] for explanation of which each Case means and more details.
