First Measurement of Energy-Dependent Inclusive Muon Neutrino Charged-Current Cross Sections on Argon with the MicroBooNE Detector.

We report a measurement of the energy-dependent total charged-current cross section σ(E_{ν}) for inclusive muon neutrinos scattering on argon, as well as measurements of flux-averaged differential cross sections as a function of muon energy and hadronic energy transfer (ν). Data corresponding to 5.3×10^{19} protons on target of exposure were collected using the MicroBooNE liquid argon time projection chamber located in the Fermilab booster neutrino beam with a mean neutrino energy of approximately 0.8GeV. The mapping between the true neutrino energy E_{ν} and reconstructed neutrino energy E_{ν}^{rec} and between the energy transfer ν and reconstructed hadronic energy E_{had}^{rec} are validated by comparing the data and MonteCarlo (MC) predictions. In particular, the modeling of the missing hadronic energy and its associated uncertainties are verified by a new method that compares the E_{had}^{rec} distributions between data and a MC prediction after constraining the reconstructed muon kinematic distributions, energy, and polar angle to those of data. The success of this validation gives confidence that the missing energy in the MicroBooNE detector is well modeled and underpins first-time measurements of both the total cross section σ(E_{ν}) and the differential cross section dσ/dν on argon.

Measurement of the antineutrino to neutrino charged-current interaction cross section ratio in MINERvA

We present measurements of the neutrino and antineutrino total charged-current cross sections on carbon and their ratio using the MINERvA scintillator-tracker. The measurements span the energy range 2-22 GeV and were performed using forward and reversed horn focusing modes of the Fermilab low-energy NuMI beam to obtain large neutrino and antineutrino samples. The flux is obtained using a sub-sample of charged-current events at low hadronic energy transfer along with precise higher energy external neutrino cross section data overlapping with our energy range between 12-22 GeV. We also report on the antineutrino-neutrino cross section ratio, Rcc, which does not rely on external normalization information. Our ratio measurement, obtained within the same experiment using the same technique, benefits from the cancellation of common sample systematic uncertainties and reaches a precision of 5% at low energy. Our results for the antineutrino-nucleus scattering cross section and for Rcc are the most precise to date in the energy range $E_{\nu} <$ 6GeV.

Measurement of low-energy neutrino cross-sections with the PEANUT experiment

The PEANUT experiment was designed to study the NuMi neutrino beam at Fermilab. The detector uses a hybrid technique, being made of nuclear emulsions and scintillator trackers. Emulsion films act as a micrometric tracking device and are interleaved with lead plates used as passive material. The detector is designed to precisely reconstruct the topology of neutrino interactions and hence to measure the different contributions to the cross section. We present here the full reconstruction and analysis of 147 neutrino interactions and the measurement of the quasi-elastic, resonance and deep-inelastic contributions to the total charged current cross section at the energies of the NuMi neutrino beam. This technique could be applied for beam monitoring in future neutrino facilities, and this paper shows its proof-of-principle.

Improved measurement of neutral current coherentπ0production on carbon in a few-GeV neutrino beam

The SciBooNE Collaboration reports a measurement of neutral current coherent neutral pion production on carbon by a muon neutrino beam with average energy 0.8 GeV. The separation of coherent from inclusive neutral pion production has been improved by detecting recoil protons from resonant neutral pion production. We measure the ratio of the neutral current coherent neutral pion production to total charged current cross sections to be (1.16 +/- 0.24) x 10-2. The ratio of charged current coherent pion to neutral current coherent pion production is calculated to be 0.14+0.30 -0.28, using our published charged current coherent pion measurement.

Measurement of inclusive neutral currentπ0production on carbon in a few-GeV neutrino beam

The SciBooNE Collaboration reports inclusive neutral current neutral pion production by a muon neutrino beam on a polystyrene target (C8H8). We obtain (7.7 \pm 0.5(stat.) \pm 0.5 (sys.)) x 10^(-2) as the ratio of the neutral current neutral pion production to total charged current cross section; the mean energy of neutrinos producing detected neutral pions is 1.1 GeV. The result agrees with the Rein-Sehgal model implemented in our neutrino interaction simulation program with nuclear effects. The spectrum shape of the neutral pion momentum and angle agree with the model. We also measure the ratio of the neutral current coherent pion production to total charged current cross section to be (0.7 \pm 0.4) x 10^(-2).

Search for charged current coherent pion production on carbon in a few-GeV neutrino beam

The SciBooNE Collaboration has performed a search for charged current coherent pion production from muon neutrinos scattering on carbon, nu{sub {mu}}{sup 12}C- {yields} {mu}{sup 12}Cpi{sup +}, with two distinct data samples. No evidence for coherent pion production is observed. We set 90% confidence level upper limits on the cross section ratio of charged current coherent pion production to the total charged current cross section at 0.67 x 10{sup -2} at mean neutrino energy 1.1 GeV and 1.36 x 10{sup -2} at mean neutrino energy 2.2 GeV.

Fine-tuning parameters to describe the total charged-current neutrino-nucleon cross section

The total charged-current (CC) (anti)neutrino-nucleon cross section is usually estimated by the sum of contributions from quasielastic scattering (QES), single-pion production through baryon resonances (RES), and deep-inelastic scattering (DIS) with an appropriate scratching of the phase space of the RES and DIS contributions. However, the resulting total cross section is very sensitive to the value of the cutoff in invariant mass of the final hadron system produced in RES and DIS. We examine available experimental data on the QES and total CC cross sections in order to extract the best-fit value for this cutoff. By using the same data set, we attempt to adjust the poorly known values of the axial mass for QES and RES.

Neutral current single π0 production induced by neutrinos with a mean energy of 1.3 GeV is measured using a 1000 ton water Cherenkov detector in the K2K long baseline neutrino experiment. The cross section for this process relative to the total charged current cross section is measured to be 0.064±0.001(stat.)±0.007(sys.). The momentum distribution of neutral current π0s from a water target is measured with high statistics for the first time.

Observation of large rapidity gap events in charged current deep inelastic scattering at HERA

Events with a large rapidity gap have been observed in e + p charged current DIS at HERA. The data collected with the ZEUS detector in the running period 1999 and 2000 correspond to an integrated luminosity of 61 pb −1 . The excess in the yield of such events over the non-diffractive DIS expectation has been compared to models of diffractive scattering in the electroweak regime. The diffractive charged current cross section for the kinematic range Q 2 > 200 GeV 2 and x P 0.05 as well as its ratio to the total charged current cross section have been calculated.

K2K NC π0 data

Neutral current single π0 production induced by neutrinos with a mean energy of 1.3 GeV is measured at a 1000 ton water Cherenkov detector as a near detector of the K2K long baseline neutrino experiment. The cross section for this process relative to the total charged current cross section is measured to be 0.063 ± 0.001 (stat.) ± 0.006 (sys.). The momentum distribution of produced π0s is measured and is found to be in good agreement with an expectation from the present knowledge of the neutrino cross sections.

Experimental upper limit on diffractive dissociation in muon-neutrino interaction with photoemulsion nuclei according to data of the E-128 experiment (Protvino)

The phenomenon of diffractive dissociation is experimentally estimated for neutrino interaction with photoemulsion nuclei. The results are based on data obtained in the SCIP experiment performed in a neutrino beam at the U-70 accelerator (Protvino). The data sample subjected to analysis included 670 charged-current events corresponding to neutrino interactions in the vertex detector. Events in which the Bjorken variable was x=0–0.1 were selected from this sample. Upon going over to the variable x′, which takes into account the nucleon mass, we set an upper limit of 0.53±0.07 on the diffractive-dissociation contribution to the total charged-current cross section.

Total neutrino and antineutrino charged current cross section measurements in 100, 160, and 200 GeV narrow band beams

Neutrino and antineutrino total charged current cross sections on iron were measured in the 100, 160, and 200 GeV narrow band beams at the CERN SPS in the energy range 10 to 200 GeV. Assuming σ/E to be constant, the values corrected for non-isoscalarity are σv/E = (0.686 ± 0.019) * 10−38 cm2/ (GeV · nucleon) and σv/E = (0.339 ± 0.010) * 10−38 cm2/ (GeV·nucleon). Between 50 and 150 GeV no energy dependence of σ/E was observed within ±3% for neutrino and ±4% for antineutrino interactions.

Measurement of total cross sections for neutrino and antineutrino charged-current interactions in hydrogen and neon

BEBC filled in turn with hydrogen, and with a neon-hydrogen mixture, was exposed to the CERN SPS wide band neutrino and antineutrino beams. The ratios of the charged-current cross sections per nucleon, σ(νH 2) σ(ν Ne) and σ( ν H 2) σ( ν Ne) , between 20 and 300 GeV were found to be 0.656 ± 0.020 and 1.425 ± 0.052, respectively. Multiplying these ratios by the revised cross sections in neon, σ(ν Ne) E = (0.723 ± 0.038) × 10 −38 cm 2/ GeV per nucleon and σ( ν Ne) E = (0.351 ± 0.019) × 10 −38 cm 2/ GeV per nucleon, and their ratio, σ( ν Ne) σ(ν Ne) = 0.485 ± 0.020 ,, yields values for the total charged-current cross sections on protons, σ(νp)/ E and σ( ν p) E , of (0.474 ± 0.029) × 10 −38 cm 2/GeV and (0.500 ± 0.032) × 10 −38 cm 2/GeV. respectively, and a value for the ratio σ( ν p) σ(ν p) of 1.053 ± 0.066.

Measurements ofνμNandν¯μNCharged-Current Total Cross Sections

Measurements of flux-normalized neutrino and antineutrino total charged-current cross sections ($\ensuremath{\sigma}$) in the energy range $45&lt;E&lt;205$ GeV are presented. We see no evidence for the anomalous sharp rise in $\frac{{\ensuremath{\sigma}}_{\overline{\ensuremath{\nu}}}}{{\ensuremath{\sigma}}_{\ensuremath{\nu}}}$ reported by earlier authors. The neutrino cross section rises linearly with energy and with $\frac{\ensuremath{\sigma}}{E}$ about 18% smaller than other measurements below 10 GeV. The average antineutrino slope at 55 GeV is consistent with measurements at low energy; however, a (20 \ifmmode\pm\else\textpm\fi{} 10)% increase is indicated over our energy range.
