νμp and νμn charged-current interactions unfolded from high energy νμ interactions in neon☆

Abstract We have developed a method to separate ν n and ν p interactions from antineutrino-neon interactions by using the final state electric charge. We present the distributions of the scaling variables x and y for ν n and ν p interactions separately , along with the ν n and ν p cross section ratios as a function of x and y . We obtain a total ν n to ν p cross section ratio of 0.45± 0.08. Our results are consistent with the predictions of the simple quark parton model.
