In the case of NC DIS, the outgoing lepton is instead a neutrino and the exchange particle is a Z boson. From Conrad, Shaevitz, and Bolton, 1998. As far as theoretical calculations go, predictions for these neutrino-induced kaon production processes have existed for several decades (Albright, 1975; Ezawa et al., 1975; Shrock, 1975; Amer, 1978; Dewan, 1981), although there have been several revised calculations in recent years (Adera et al., 2010; Alam et al., 2010, 2012). internal structure of the target. In the most common highenergy interaction, the neutrino can scatter off an individual quark inside the nucleon, a process called deep inelastic scattering (DIS). An excellent review of this subject has been previously published in this journal (Conrad, Shaevitz, and Bolton, 1998), therefore we provide only a brief summary of the DIS cross section, relevant kinematics, and most recent experimental measurements here. G. Outlook A. Deep inelastic scattering In summary, neutrino scattering at intermediate energies is notoriously complex and the level to which these contributing processes have been studied remains incomplete (Benhar, 2010; Alvarez-Ruso, 2011b). Improved experimental measurements and theoretical calculations will be especially important for reducing systematics in future precision neutrino oscillation experiments. Luckily, such studies are already underway making use of new intense accelerator-based sources of neutrinos. However, for such updated cross section measurements to be robust, they must be accompanied by an equally precise knowledge of the incoming neutrino flux. Improved hadro-production measurements are key to providing the level of precision necessary. In addition, further scrutiny of nuclear effects in intermediate energy neutrino and antineutrino interactions is absolutely essential. Analysis of data from the MINERA experiment will soon enable the first detailed look at nuclear effects in neutrino interactions. Together, theoretical advances and new data taken on a variety of nuclear targets from the ArgoNeuT, K2K, MicroBooNE, MINERA, MiniBooNE, MINOS, NOMAD, NOvA, and SciBooNE experiments should provide both a necessary and broad foundation going into the future. In order to make progress in our understanding of this energy regime and provide the most clarity, experiments should strive to report what they directly detect in the final state, for exam...
