    A different view of deep inelastic electron-proton scattering

    Get PDF
    Deep inelastic electron-proton scattering is analyzed in the target rest frame using a theoretical approach suitable to describe many-body systems of {\em bound} constituents subject to {\em interactions}. At large three-momentum transfer \magq, this approach predicts the onset of scaling in the variable \yt=\nu-\magq, where ν\nu denotes the energy transfer. The present analysis shows that the data, plotted at constant \magq, exhibit a remarkable scaling behavior in \yt and manifestly display the presence of sizable interaction effects.Comment: 8 pages, 4 figures.

    Neutrino-nucleus cross section in the impulse approximation regime

    Full text link
    In the impulse approximation regime the nuclear response to a weakly interacting probe can be written in terms of the measured nucleon structure fuctions and the target spectral function, yielding the energy and momentum distribution of the constituent nucleons. We discuss a calculation of charged current neutrino-oxygen interactions in the quasielastic channel, carried out within nuclear many body theory. The proposed approach, extensively and successfully employed in the analysys of electron-nucleus scattering data, allows for a parameter free prediction of the neutrino-nucleus cross section, whose quantitative understanding will be critical to the analysis of the next genaration of high precision neutrino oscillation experiments.Comment: 4 pages, 3 Figs.
