Description
The next generation of long-baseline neutrino experiments requires a high precision understanding of neutrino-nucleus interactions. The MINERvA experiment at Fermilab was designed to provide this increased understanding with accurate measurements of these interactions that then guide the development of robust interaction models. In particular, cross-section measurements play a central role in advancing these models used in the measurement of oscillation parameters. A more powerful approach than measuring the cross-section in one beam is to extract the same cross-section measurement in two different beams incident on the same detector. This allows for two measurements of the same cross-section using identical detector technology, simulation, and measurement extraction procedures, while the flux of the incoming particles differs depending on the incident beam. This provides a unique opportunity to assess the impact that the changing flux has on the measurement, serving as an additional benchmark for tuning cross-section models.
This work presents a measurement of the inclusive antineutrino (and neutrino) cross-sections, in terms of muon kinematics, on the hydrocarbon tracker region of the MINERvA detector with two different beams, one peaked at 3GeV and one peaked at 6GeV. This inclusive measurement as a function of muon transverse and longitudinal momenta will be presented along with comparisons to different oscillation experiment model predictions.
