Measurement of the muon neutrino inclusive charged-current cross section in the energy range of 1–3 GeV with the T2K INGRID detector
We report a measurement of the νμ-nucleus inclusive charged-current cross section (¼ σcc) on iron using
data from the INGRID detector exposed to the J-PARC neutrino beam. The detector consists of 14 modules
in total, which are spread over a range of off-axis angles from 0° to 1.1°. The variation in the neutrino
energy spectrum as a function of the off-axis angle, combined with event topology information, is used to
calculate this cross section as a function of neutrino energy. The cross section is measured to be
σccð1.1 GeVÞ ¼ 1.10 0.15 ð10−38 cm2=nucleonÞ, σccð2.0 GeVÞ ¼ 2.07 0.27 ð10−38 cm2=nucleonÞ,
and σccð3.3 GeVÞ ¼ 2.29 0.45 ð10−38 cm2=nucleonÞ, at energies of 1.1, 2.0, and 3.3 GeV, respectively.
These results are consistent with the cross section calculated by the neutrino interaction generators
currently used by T2K. More importantly, the method described here opens up a new way to determine the
energy dependence of neutrino-nucleus cross sections
