◆ HOWEVER also understanding axial-vector nucleus interactions!! ◆ The precision with which we measure neutrino oscillation parameters limited by our knowledge of ν - nucleus interactions.
In a two-detector experiment, use observed neutrino energy spectra in ND to predict spectra in FD.
Significant challenges from ν - nucleus interactions to do this!! 2 Knowledge of ν-Nucleus Interactions How do these interactions manifest themselves in our detectors constructed of heavy nuclei?
Yc-like (Ed): Yield in our detectors is dependent on
φ(Ε’≥ Εd) Neutrino Flux
X
σc,d,e..(Ε’≥ Εd) Neutrino Cross Section X
Nucc,d,e.. (E’≥ Ed) Neutrino Nuclear Effects
Yc-like (Ed): What we find in our detectors is not necessarily what was produced at the interaction. The physics we are after depends on what was produced! 3 Flux must be calculatedWhat (MC+data)are the challenges
