Proposal to Perform a High-Statistics Neutrino Scattering Experiment Using a Fine-grained Detector
Minerva Collaboration
Physics , 2004,
Abstract: The NuMI facility at Fermilab will provide an extremely intense beam of neutrinos for the MINOS neutrino-oscillation experiment. The spacious and fully-outfitted MINOS near detector hall will be the ideal venue for a high-statistics, high-resolution $\nu$ and $\nubar$--nucleon/nucleus scattering experiment. The experiment described here will measure neutrino cross-sections and probe nuclear effects essential to present and future neutrino-oscillation experiments. Moreover, with the high NuMI beam intensity, the experiment will either initially address or significantly improve our knowledge of a wide variety of neutrino physics topics of interest and importance to the elementary-particle and nuclear-physics communities.
Measurement of electron neutrino CCQE-like cross-section in MINERvA
Jeremy Wolcott,for the MINERvA collaboration
Physics , 2015,
Abstract: The electron-neutrino charged-current quasi-elastic (CCQE) cross-section on nuclei is an important input parameter to appearance-type neutrino oscillation experiments. Current experiments typically work from the muon neutrino cross-section and apply corrections from theoretical arguments to obtain a prediction for the electron neutrino cross-section, but to date there has been no experimental verification of the estimates for this channel at an energy scale appropriate to such experiments. We present a preliminary result from the MINERvA experiment on the first measurement of an exclusive reaction in few-GeV electron neutrino interactions, namely, the cross-section for a CCQE-like process. The result is given both as differential cross-sections vs. the electron energy, electron angle, and $Q^{2}$, as well as a total cross-section vs. neutrino energy.
Implications of recent MINER$ν$A results for neutrino energy reconstruction
Jeremy Wolcott,for the MINERvA collaboration
Physics , 2015,
Abstract: Among the most important tasks of neutrino oscillation experiments is correctly estimating the parent neutrino energy from the by-products of their interactions. Large uncertainties in our current understanding of such processes can significantly hamper this effort. We explore several recent measurements made using the \mnv{} detector in the few-GeV NuMI muon neutrino beam at Fermilab: the differential cross-section vs. $Q^2$ for charged-current quasi-elastic scattering, the differential cross-sections vs. pion angle and pion kinetic energy for resonant single charged pion production, and the differential cross-sections vs. pion angle and kinetic energy for coherent pion production. We furthermore discuss their implications for energy reconstruction in oscillation measurements.
Electron neutrino charged-current quasielastic scattering in the MINERvA experiment
Jeremy Wolcott,for the MINERvA collaboration
Physics , 2015,
Abstract: The electron-neutrino charged-current quasielastic (CCQE) cross section on nuclei is an important input parameter to appearance-type neutrino oscillation experiments. Current experiments typically work from the muon neutrino cross section and apply corrections from theoretical arguments to obtain a prediction for the electron neutrino cross section, but to date there has been no experimental verification of the estimates for this channel at an energy scale appropriate to such experiments. We present the first measurement of an exclusive reaction in few-GeV electron neutrino interactions, namely, the cross section for a CCQE-like process, made using the MINERvA detector. The result is given as differential cross-sections vs. the electron energy, electron angle, and square of the four-momentum transferred to the nucleus, $Q^2$. We also compute the ratio to a muon neutrino cross-section in $Q^2$ from MINERvA. We find satisfactory agreement between this measurement and the predictions of the GENIE generator.
Neutrino Scattering Uncertainties and their Role in Long Baseline Oscillation Experiments
The MINERvA Collaboration,D. A. Harris
Physics , 2004,
Abstract: The field of oscillation physics is about to make an enormous leap forward in statistical precision: first through the MINOS experiment in the coming year, and later through the NOvA and T2K experiments. Because of the relatively poor understanding of neutrino interactions in the energy ranges of these experiments, there are systematics that can arise in interpreting far detector data that can be as large as or even larger than the expected statistical uncertainties. We describe how these systematic errors arise, and how specific measurements in a dedicated neutrino scattering experiment like MINERvA can reduce the cross section systematic errors to well below the statistical errors.
Quasi-Elastic Scattering in MINERvA
Kevin S. McFarland,for the MINERvA Collaboration
Physics , 2011, DOI: 10.1063/1.3661565
Abstract: Determination of the quasi-elastic scattering cross-section over a broad range of neutrino energies, nuclear targets and Q^2 is a primary goal of the MINERvA experiment. We present preliminary comparisons of data and simulation in a sample rich in anti-{\nu}_{\mu}+p\rightarrow{\mu}+n events from approximately one eighth of the total anti-{\nu} events collected by MINERvA to date. We discuss future plans for quasi-elastic analyses in MINERvA.
Measuring the NuMI Beam Flux for MINERvA
Melissa T. Jerkins,for the MINERvA Collaboration
Physics , 2011, DOI: 10.1063/1.3661618
Abstract: MINERvA is employing multiple tools to understand its neutrino beam flux. We utilize external hadron production data, but we also depend heavily on in situ techniques in which we reduce our hadron production uncertainties by tuning our Monte Carlo to both MINERvA detector data and muon monitor data.
Nuclear Target Cross Section Ratios at MINERvA
Brian G. Tice,for the MINERvA Collaboration
Physics , 2014,
Abstract: Measurements of $\nu_{\mu}$ inclusive charged-current cross section ratios on carbon, iron, and lead relative to scintillator are presented. Data for the analysis were collected by the fine-grained MINERvA detector in the NuMI beamline at Fermilab. This is the first direct measurement of nuclear dependence in neutrino scattering. The ratios show a depletion at low Bjorken $x$ and enhancement at large $x$, both of which increase with the nucleon number of the target. The data exhibit trends not found in GENIE, a standard neutrino-nucleus event generator, or alternative models of nuclear modification to inelastic structure functions.
MINERvA Status and Event Reconstruction
Gabriel N. Perdue,for the MINERvA Collaboration
Physics , 2011,
Abstract: MINERvA (Main INjector ExpeRiment v-A) is a few-GeV neutrino scattering experiment that began taking data in the NuMI beam at Fermilab (FNAL) in the Fall of 2009. MINERvA employs a fine-grained detector, with an eight ton active target region composed of plastic scintillator. It also uses nuclear targets composed of carbon, iron, and lead placed upstream of the active region to measure v-A dependence. The experiment will provide important inputs for neutrino oscillation experiments and a pure weak probe of nuclear structure. We offer a set of initial kinematic distributions of interest and provide a summary of current operations and event reconstruction status.
