Influence of Cross-Sectional Uncertainty on Sensitivity Studies of DUNE and T2HK Experiments

The ultimate objectives of ongoing and upcoming neutrino experiments are the precise measurement mixing parameters confirmation mass hierarchy. systematic inaccuracy in cross-section models introduces estimation. It is important to secure a large decrease uncertainties, particularly those relating cross-section, neutrino-nucleus interactions, neutrino-energy reconstruction, order achieve these ambitious goals. In this research article, we use three alternative event generators, GENIE, NuWro, GiBUU, analyze sensitivity studies T2HK, DUNE, combined T2HK for hierarchy, CP violation, octant degeneracy caused by uncertainties. generators separate independent.
