Measurement of inclusive charged current interactions on carbon in a few-GeV neutrino beam
The SciBooNE Collaboration reports a measurement of inclusive charged current
interactions of muon neutrinos on carbon with an average energy of 0.8 GeV
using the Fermilab Booster Neutrino Beam. We compare our measurement with two
neutrino interaction simulations: NEUT and NUANCE. The charged current
interaction rates (product of flux and cross section) are extracted by fitting
the muon kinematics, with a precision of 6-15% for the energy dependent and 3%
for the energy integrated analyses. We also extract CC inclusive interaction
cross sections from the observed rates, with a precision of 10-30% for the
energy dependent and 8% for the energy integrated analyses. This is the first
measurement of the CC inclusive cross section on carbon around 1 GeV. These
results can be used to convert previous SciBooNE cross section ratio
measurements to absolute cross section values.Comment: 21 pages, 16 figures. Accepted by Phys. Rev. D. Minor revisions to

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_\mu
^{12}C \to \mu^- ^{12}C \pi^+, 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\times 10^{-2} at mean neutrino
energy 1.1 GeV and 1.36\times 10^{-2} at mean neutrino energy 2.2 GeV.Comment: 18 pages, 16 figures, Minor revisions to match version accepted for

Measurement of neutral current coherent neutral pion production 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.Comment: seven pages, 6 fiure

Measurement of Inclusive Neutral Current Neutral Pion Production 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).Comment: 17 pages, 23 figures, accepted by Phys. Rev.

Measurement of K(+) production cross section by 8 GeV protons using high-energy neutrino interactions in the SciBooNE detector
The SciBooNE Collaboration reports K[superscript +] production cross section and rate measurements using high-energy daughter muon neutrino scattering data off the SciBar polystyrene (C[subscript 8]H[subscript 8]) target in the SciBooNE detector. The K[superscript +] mesons are produced by 8 GeV protons striking a beryllium target in Fermilab Booster Neutrino Beam line (BNB). Using observed neutrino and antineutrino events in SciBooNE, we measure d[superscript 2]σ/dpdΩ=(5.34±0.76)  mb/(GeV/c×sr) for p+Be→K[superscript +]+X at mean K[superscript +] energy of 3.9 GeV and angle (with respect to the proton beam direction) of 3.7 degrees, corresponding to the selected K[superscript +] sample. Compared to Monte Carlo predictions using previous higher energy K[superscript +] production measurements, this measurement, which uses the NUANCE neutrino interaction generator, is consistent with a normalization factor of 0.85±0.12. This agreement is evidence that the extrapolation of the higher energy K[superscript +] measurements to an 8 GeV beam energy using Feynman scaling is valid. This measurement reduces the error on the K[superscript +] production cross section from 40% to 14%.Japan.

Dual baseline search for muon antineutrino disappearance at 0.1 eV² < <{\Delta}m² < 100 eV²
The MiniBooNE and SciBooNE collaborations report the results of a joint search for short baseline disappearance of ν̅[subscript μ] at Fermilab’s Booster Neutrino Beamline. The MiniBooNE Cherenkov detector and the SciBooNE tracking detector observe antineutrinos from the same beam, therefore the combined analysis of their data sets serves to partially constrain some of the flux and cross section uncertainties. Uncertainties in the ν[subscript μ] background were constrained by neutrino flux and cross section measurements performed in both detectors. A likelihood ratio method was used to set a 90% confidence level upper limit on ν̅[subscript μ] disappearance that dramatically improves upon prior limits in the Δm[superscript 2]=0.1–100  eV[superscript 2] region
