Abstract
We report measurements of the flux-integrated ν̅μ and ν̅μ + νμ charged-current cross-sections on water and hydrocarbon targets using the T2K anti-neutrino beam with a mean beam energy of 0.86 GeV. The signal is defined as the (anti-)neutrino charged-current interaction with one induced μ± and no detected charged pion or proton. These measurements are performed using a new WAGASCI module recently added to the T2K setup in combination with the INGRID Proton Module. The phase space of muons is restricted to the high-detection efficiency region, pμ>400 MeV/c and θμ<30∘, in the laboratory frame. An absence of pions and protons in the detectable phase spaces of pπ>200 MeV/c, θπ<70∘ and pp>600 MeV/c, θp<70∘ is required. In this paper, both the ν¯¯¯μ cross-sections and ν¯¯¯μ+νμ cross-sections on water and hydrocarbon targets and their ratios are provided by using the D’Agostini unfolding method. The results of the integrated ν¯¯¯μ cross-section measurements over this phase space are σH2O=(1.082±0.068(stat.)+0.145−0.128(syst.))×10−39cm2/nucleon, σCH=(1.096±0.054(stat.)+0.132−0.117(syst.))×10−39cm2/nucleon, and σH2O/σCH=0.987±0.078(stat.)+0.093−0.090(syst.). The ν¯¯¯μ+νμ cross-section is σH2O=(1.155±0.064(stat.)+0.148−0.129(syst.))×10−39cm2/nucleon, σCH=(1.159±0.049(stat.)+0.129−0.115(syst.))×10−39cm2/nucleon, and σH2O/σCH=0.996±0.069(stat.)+0.083−0.078(syst.).
