Nuclear structure functions in the large- x large- Q2 kinematic region in neutrino deep inelastic scattering

M. Vakili, C. G. Arroyo, P. Auchincloss, Lucyna de Barbaro et autres

Data from the CCFR E770 neutrino deep inelastic scattering experiment at Fermilab contain events with a large Bjorken x $(x>0.7)$ and high momentum transfer $[{Q}^{2}>50 (\mathrm{GeV}{/c)}^{2}].$ A comparison of the data with a model based on no nuclear effects at large x …

High statistics search for v{sub e}({bar v}{sub e}){r_arrow}v{sub {tau}}({bar v}{sub {tau}}) oscillations

Rob Johnson, M. Vakili, Alexandru Romosan, C. G. Arroyo et autres

We present new limits on v{sub e}({bar v}{sub e}){r_arrow}v{sub {tau}}({bar v}{sub {tau}}) and v{sub e}({bar v}{sub e}){r_arrow}v{sub s} oscillations by searching for v{sub e} disappearance in the high-energy wideband CCFR neutrino beam. Sensitivity to v{sub {tau}} appearance comes from {tau} decay modes …

Measurement of αs(Q2) from the Gross–Llewellyn Smith Sum Rule

J. H. Kim, Deborah A. Harris, C. G. Arroyo, Lucyna de Barbaro et autres

We extract a set of values for the Gross--Llewellyn Smith sum rule at different values of 4-momentum transfer squared ( ${Q}^{2}$), by combining revised CCFR neutrino data with data from other neutrino deep-inelastic scattering experiments for $1<{Q}^{2}<15{\mathrm{GeV}}^{2}{/c}^{2}$. A comparison with the order …

ROBERT ALAN JOHNSON, M. Vakili, J.H. Kim, C. G. Arroyo et autres

We extract a set of values for the Gross{endash}Llewellyn Smith sum rule at different values of 4-momentum transfer squared (Q{sup 2} ), by combining revised CCFR neutrino data with data from other neutrino deep-inelastic scattering experiments for 1{lt}Q{sup 2}{lt}15 GeV{sup 2}/c{sup 2} …

Measurements of the longitudinal structure function and |V_cs| in the CCFR experiment

Ccfr, U. K. Yang, Cynthia Kay McNulty, C. G. Arroyo et autres

Measurements of charged current neutrino and anti-neutrino nucleon interactions in the CCFR detector are used to extract the structure functions, F_2, xF_3(nu), xF_3(nubar) and R(longitudinal) in the kinematic region 0.01<x<0.6 and 1<Q^2<300 GeV^2. The new measurements of R in the x<0.1 region …

Improved Determination of αs From Neutrino-Nucleon Scattering

W. Seligman, C. G. Arroyo, Lucyna de Barbaro, P. de Barbaro et autres

We present an improved determination of the proton structure functions ${F}_{2}$ and ${\mathrm{xF}}_{3}$ from the Columbia-Chicago-Fermilab-Rochester Collaboration $\ensuremath{\nu}\ensuremath{-}\mathrm{Fe}$ deep inelastic scattering experiment. Comparisons to corrected high-statistics charged-lepton scattering results for ${F}_{2}$ from the NMC, E665, SLAC, and BCDMS experiments indicate good agreement …

High Statistics Search for νμ(ν¯μ)→νe(ν¯e) Oscillations in the Small Mixing Angle Regime

Alexandru Romosan, C. G. Arroyo, Lucyna de Barbaro, P. de Barbaro et autres

Limits on ${\ensuremath{\nu}}_{\ensuremath{\mu}}({\overline{\ensuremath{\nu}}}_{\ensuremath{\mu}})\ensuremath{\rightarrow}{\ensuremath{\nu}}_{e}({\overline{\ensuremath{\nu}}}_{e})$ oscillations based on a statistical separation of ${\ensuremath{\nu}}_{e}N$ charged current interactions in the CCFR detector at Fermilab are presented. Neutrino energies range from 30 to 600 GeV with a mean of 140 GeV, and ${\ensuremath{\nu}}_{\ensuremath{\mu}}$ flight lengths vary from …

We present limits on ${\ensuremath{\nu}}_{\ensuremath{\mu}}({\overline{\ensuremath{\nu}}}_{\ensuremath{\mu}})\ensuremath{\rightarrow}{\ensuremath{\nu}}_{\ensuremath{\tau}}({\overline{\ensuremath{\nu}}}_{\ensuremath{\tau}})$ and ${\ensuremath{\nu}}_{\ensuremath{\mu}}({\overline{\ensuremath{\nu}}}_{\ensuremath{\mu}})\ensuremath{\rightarrow}{\ensuremath{\nu}}_{e}({\overline{\ensuremath{\nu}}}_{e})$ oscillations based on a study of inclusive $\ensuremath{\nu}N$ interactions performed using the CCFR massive coarse-grained detector in the Fermilab Tevatron Quadrupole Triplet neutrino beam. The sensitivity to oscillations is from the difference in the longitudinal …
