Session X10: Invited Session: Determining Neutrino Cross Sections

Experimental Results on Neutrino Scattering

High intensity beams and new detectors are enabling us to gather new information about reactions of GeV neutrinos on nuclei, at the transition between elastic and inelastic scattering. Accurate modeling of these complex reactions will benefit greatly from this data. I will review results and capabilities of current and near future experiments, and will discuss how this data can help to sharpen the emerging picture of neutrino interactions.   

Neutrino-Nucleon (Nucleus) Scattering for non-Neutrino Physics: The case of Neutral Current induced Photon Production

Previously, I have studied the photon production in neutral current (NC) neutrino-nucleon (nucleus) scattering, and addressed its relevance to the MiniBooNE anomaly. (MiniBooNE is a short baseline neutrino oscillation experiment at FNAL.) In this talk I will review this topic, and discuss its connection to parity violating electron-nucleon scattering. Such electron scattering has been used in Qweak experiment at Jlab to measure precisely the proton weak charge. In addition, the nucleon-to-resonance excitations induced by both weak and electromagnetic currents play important roles in the NC photon production process. Understanding all these excitations in a unified microscopic framework is challenging. I will mention our effort along this line, and emphasize the complementarity between neutrino and electron scattering measurements of these excitations and their importance to improve our knowledge of nucleon structure.
