Knowledge of the neutrino flux produced by Neutrinos at Main Injector (NuMI) beamline is essential to oscillation and interaction measurements MINERvA, MINOS+, NOvA MicroBooNE experiments Fermi National Accelerator Laboratory.

Two different nuclear-medium effects are isolated using a low three-momentum transfer subsample of neutrino-carbon scattering data from the MINERvA neutrino experiment. The observed hadronic energy in charged-current $\nu_\mu$ interactions is combined with muon kinematics to permit separation quasielastic and $\Delta$(1232) resonance processes. First, we observe small cross section at very that matches expected screening effect long-range nucleon correlations. Second, additions event rate...

Charged pion production via charged-current ${\ensuremath{\nu}}_{\ensuremath{\mu}}$ interactions on plastic scintillator (CH) is studied using the MINERvA detector exposed to NuMI wideband neutrino beam at Fermilab. Events with hadronic invariant mass $W<1.4\text{ }\text{ }\mathrm{GeV}$ and $W<1.8\text{ are selected in separate analyses: lower $W$ cut isolates single production, which expected occur primarily through $\mathrm{\ensuremath{\Delta}}(1232)$ resonance, while results from higher...
Neutrino-induced coherent charged pion production on nuclei νμA→μ(±)π(∓)A is a rare, inelastic interaction in which small squared four-momentum |t| transferred to the recoil nucleus, leaving it intact reaction. In scintillator tracker of MINERvA, we remove events with evidence particles from nuclear breakup and reconstruct final-state muon. We select low isolate sample rich candidates. By selecting events, produce model-independent measurement differential cross section for scattering...
