67. Hadron Production Measurements for Neutrino Experiments

In current measurements of accelerator-based neutrino experiments, neutrino flux uncertainties represent a leading systematic uncertainty. Neutrino beams are created from the decays of secondary hadrons produced in hadron-nucleus interactions. Primary and secondary hadron production processes for neutrino beams are the leading source of flux uncertainty. Therefore, precise hadron production...

One of the leading sources of systematic uncertainty in neutrino experiments is the modeling of the neutrino flux. Neutrino flux uncertainties are dominated by hadron scattering and hadron production cross section uncertainties, and new, dedicated measurements are needed. The EMPHATIC collaboration aims to measure the forward-scattering and production of hadrons for a variety of beam momenta...

28. ENUBET: a monitored neutrino beam for high precision cross section measurements

Talk

The main source of systematic uncertainty on neutrino cross section measurements at the GeV scale is represented by the poor knowledge of the initial flux. The goal of cutting down this uncertainty to 1% can be achieved through the monitoring of charged leptons produced in association with neutrinos, by properly instrumenting the decay region of a conventional narrow-band neutrino beam. Large...

70. A substandard candle: the low-nu method at few-GeV neutrino energies

Talk

The low-nu method has been discussed as a "standard candle" in the context of accelerator neutrino beam experiments which require a precise understanding of the neutrino flux. The method utilizes a sub-sample of events where there is low energy-transfer to the nucleus, and requires that the interaction cross section is approximately constant for this sub-sample as a function of neutrino...

High-intensity neutrino beams are an essential tool to study neutrino physics. Both neutrino oscillation experiments and cross-section measurements require a precise prediction of the neutrino flux. MINERvA is a dedicated on-axis high-statistics neutrino-nucleus scattering experiment in the NuMI beamline at Fermilab with an intensive campaign to study the neutrino flux. We performed several...
