Measurements of the ${\nu }_{\mu }$ and ${\bar{\nu }}_{\mu }$-induced Coherent Charged Pion Production Cross Sections on ${}^{12}C$ by the T2K experiment

Abstract

We report an updated measurement of the ${\nu }_{\mu }$-induced, and the first measurement of the ${\bar{\nu }}_{\mu }$-induced coherent charged pion production cross section on ${}^{12}C$ nuclei in the T2K experiment. This is measured in a restricted region of the final-state phase space for which $p_{\mu ,\pi }>0.2$ GeV, $\cos ({\theta }_{\mu })>0.8$ and $\cos ({\theta }_{\pi })>0.6$, and at a mean (anti)neutrino energy of 0.85 GeV using the T2K near detector. The measured ${\nu }_{\mu }$ CC coherent pion production flux-averaged cross section on ${}^{12}C$ is $(2.98\pm 0.37(stat.)\pm 0.31(syst.)\begin{array}{c}+0.49\\ -0.00\end{array}({\mathrm{Q}}^2\mathrm{model}))\times 10^{-40}{\mathrm{cm}}^2$. The new measurement of the ${\bar{\nu }}_{\mu }$-induced cross section on ${}^{12}C$ is $(3.05\pm 0.71(stat.)\pm 0.39(syst.)\begin{array}{c}+0.74\\ -0.00\end{array}({\mathrm{Q}}^2\mathrm{model}))\times 10^{-40}{\mathrm{cm}}^2$. The results are compatible with both the NEUT 5.4.0 Berger-Sehgal (2009) and GENIE 2.8.0 Rein-Sehgal (2007) model predictions.
