Measurement of ν μ charged-current inclusive π 0 production in the NOvA near detector

Résumé fourni par la source

Cross sections for the interaction ${\ensuremath{\nu}}_{\ensuremath{\mu}}A\ensuremath{\rightarrow}{\ensuremath{\mu}}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}X$ with neutrino energies between 1 and 5 GeV are measured using a sample of 165,000 selected events collected in the NOvA experiment's near detector, a hydrocarbon-based detector exposed to the Neutrinos from the Main Injector beam at the Fermi National Accelerator Laboratory. Results are presented as a flux-averaged total cross section and as differential cross sections in the momenta and angles of the outgoing muon and ${\ensuremath{\pi}}^{0}$, the total four-momentum transfer, and the invariant mass of the hadronic system. Comparisons are made with predictions from a reference version of the genie neutrino interaction generator. The measured total cross section of ($3.57\ifmmode\pm\else\textpm\fi{}0.44)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}39}\text{ }\text{ }{\mathrm{cm}}^{2}$ is 7.5% higher than the genie prediction, but is consistent within experimental errors.
