Conclusion We want to study the cross-section model, but we don’t want to implement every models in the world in our simulation… We want theorists to use our data, but flux-unfolding (model-dependent process) lose details of measurements… Now, all modern experiments publish flux-integrated differential cross-section à Detector efficiency corrected event rate à Flux and FSI are convoluted à Theorists can reproduce the data with neutrino flux tables from experimentalists à Minimum model dependent, useful for nuclear theorists These data play major roles to study/improve neutrino interaction models by theorists Teppei Katori, Queen Mary University of London 2015/11/30 5
