Measurement of ${\bar{\nu }}_{\mu }$ and ${\nu }_{\mu }$ charged current inclusive cross sections and their ratio with the T2K off-axis near detector

K. Abe, J. Amey, C. Andreopoulos +291

We report a measurement of cross section $\sigma ({\nu }_{\mu }+\mathrm{nucleus}\to {\mu }^{-}+X)$ and the first measurements of the cross section $\sigma ({\bar{\nu }}_{\mu }+\mathrm{nucleus}\to {\mu }^{+}+X)$ and t…
