The popular GENIE Generator product is used by nearly all accelerator neutrino experiments and it plays a key role in the exploitation of neutrino data. The Generator implements a modern software framework and it includes state-of-the-art physics modules. It captures the latest results of the GENIE global analysis of neutrino scattering data and includes several tunes that were produced using the proprietary Comparisons and Tuning products. The GENIE physics model is universal and comprehensive: It handles all neutrinos and targets, and all processes relevant from MeV to PeV energy scales. The Generator includes several tools (flux drivers, detector geometry navigators, specialized event generation apps, event reweighting engines) to simulate complex experimental setups in full detail and to support generator-related analysis tasks.
We observed that for some tuned eN RES GV FF, the delta peak is well described without non-res background. We add a new parameter, Wcutmin, to cut the region where we believe non-res background is not necessary. The default is set to 0 to not alter the existing configurations.
If needed, a new parameter can be used to change the coverage of the non-res bkg in W.
The example attached considers Wmin of 1.4GeV:

The expected behaviour is observed when using default of 0:
