| contents | A deep understanding of neutrino-nucleus interaction is crucial for the precise measurement of neutrino oscillation parameters and cross section measurements. Various nuclear effects, such as initial state effects (IS) and Final state interactions (FSI), make neutrino interactions more complicated. To probe the impacts of the nuclear effects, a separate study of FSI and IS is required. A set of variables known as Centre-of-momentum (c.m.) variables ($θ_{c.m.}$ and $E_{c.m.}$) provides a unique approach to isolate the FSI effect with minimal sensitivity to IS. This work presents the importance of c.m. variables in neutrino-induced eta ($η$) meson production in the DUNE near detector. $θ_{c.m.}$ is an important parameter to improve the FSI modeling, while $E_{c.m.}$ helps in isolating high-purity neutrino-Hydrogen events. The study of $η$ production in neutrino interactions helps in understanding the theoretical descriptions of higher resonance states. |
