New neutrino interaction cross-section measured in T2K shows discrepancy with expectations
T2K published a new measurement of the differential cross sections of muon neutrino charged-current interactions on carbon with a single positively charged pion. While agreement with the models is generally good, data shows a significant discrepancy in the so-called low Q2 region.
The new measurements of the single and double differential cross sections of muon neutrino charged-current interactions on carbon with a single positively charged pion measured in T2K have been published. A significant difference in the shape of experimental results and the predictions is observed. The pronounced model suppression at low Q2 is an indication of deficiencies in the nuclear model describing the carbon nuclei hit by the neutrinos.
