SciBooNE and MiniBooNE collaborations(Mahn, K. B. M. et al), Catala-Perez, J., Gomez-Cadenas, J. J., & Sorel, M. (2012). Dual baseline search for muon neutrino disappearance at 0.5 eV(2) < Delta m(2) < 40 eV(2). Phys. Rev. D, 85(3), 032007–10pp.
Abstract: The SciBooNE and MiniBooNE collaborations report the results of a nu(mu) disappearance search in the Delta m(2) region of 0.5-40 eV(2). The neutrino rate as measured by the SciBooNE tracking detectors is used to constrain the rate at the MiniBooNE Cherenkov detector in the first joint analysis of data from both collaborations. Two separate analyses of the combined data samples set 90% confidence level (CL) limits on nu(mu) disappearance in the 0.5-40 eV(2) Delta m(2) region, with an improvement over previous experimental constraints between 10 and 30 eV(2).

SciBooNE Collaboration(Cheng, G. et al), Catala-Perez, J., Gomez-Cadenas, J. J., & Sorel, M. (2011). Measurement of K(+) production cross section by 8 GeV protons using high-energy neutrino interactions in the SciBooNE detector. Phys. Rev. D, 84(1), 012009–22pp.
Abstract: The SciBooNE Collaboration reports K(+) production cross section and rate measurements using high-energy daughter muon neutrino scattering data off the SciBar polystyrene (C(8)H(8)) target in the SciBooNE detector. The K(+) 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(2)sigma/dpd Omega = (5.34 +/- 0.76) mb/(GeV/c x sr) for p + Be -> K(+) + X at mean K(+) energy of 3.9 GeVand angle (with respect to the proton beam direction) of 3.7 degrees, corresponding to the selected K(+) sample. Compared to Monte Carlo predictions using previous higher energy K(+) 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(+) measurements to an 8 GeV beam energy using Feynman scaling is valid. This measurement reduces the error on the K(+) production cross section from 40% to 14%.

SciBooNE Collaboration(Kurimoto, Y. et al), Catala-Perez, J., Gomez-Cadenas, J. J., & Sorel, M. (2010). Improved measurement of neutral current coherent pi(0) production on carbon in a few-GeV neutrino beam. Phys. Rev. D, 81(11), 111102–6pp.
Abstract: The SciBooNE Collaboration reports a measurement of neutral current coherent pi(0) production on carbon by a muon neutrino beam with average energy 0.8 GeV. The separation of coherent from inclusive pi(0) production has been improved by detecting recoil protons from resonant pi(0) production. We measure the ratio of the neutral current coherent pi(0) production to total charged current cross sections to be 1.16 +/- 0.24) x 10(-2). The ratio of charged current coherent pi(+) to neutral current coherent pi(0) production is calculated to be 0.14(-0.28)(+0.30), using our published charged current coherent pion measurement.

Abstract: The SciBooNE Collaboration reports inclusive neutral current neutral pion production by a muon neutrino beam on a polystyrene target (C8H8). We obtain (7.7 +/- 0.5(stat) +/- 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 pi(0) 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 +/- 0.4) X 10(-2).

SciBooNE Collaboration(Nakajima, Y. et al), Catala-Perez, J., Gomez-Cadenas, J. J., & Sorel, M. (2011). Measurement of inclusive charged current interactions on carbon in a few-GeV neutrino beam. Phys. Rev. D, 83(1), 012005–21pp.
Abstract: We report 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 charged current 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 charged current 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.
