S. R. Mishra,S.A. Rabinowitz,C. G. Arroyo,K.T. Bachmann,R. E. Blair,C. Foudas,Bruce J. King,W.C. Lefmann,W.C. Leung,E. Oltman,P.Z. Quintas,F. J. Sciulli,B. G. Seligman,M. H. Shaevitz,F. S. Merritt,M. J. Oreglia,Bruce Schumm,R. H. Bernstein,F. Borcherding,H. E. Fisk,M. J. Lamm,W. Marsh,K. W. Merritt,H. Schellman,D. D. Yovanovitch,A. Bodek,H. S. Budd,P. de Barbaro,W. K. Sakumoto,P.H. Sandler,W. H. Smith +30 more
TL;DR: This is the first demonstration of the W-Z destructive interference from neutrino tridents, and rules out, at 99% C.L., the V-A prediction without the interference.
Journal ArticleDOI

Smith,Panagiotis Spentzouris,E. G. Stern,M. Vakili,Unki Yang,Ji-Young Yu +33 more
TL;DR: In this paper, an improved determination of the proton structure functions from the CCFR $-Fe deep inelastic scattering (DIS) experiment was presented. But the results were not as good as those obtained in this paper.
Journal ArticleDOI

TL;DR: In this article, the first next-to-leading-order QCD analysis of neutrino charm production was presented, using a sample of 6090ν====== μーテ � −0.232====== − 0.477====== + 0.063====== +0.018====== +1.70±0.19 GeV/c2.

TL;DR: A high-statistics study by the Columbia-Chicago-Fermilab-Rochester Collaboration of opposite-sign dimuon events induced by neutrino-nucleon scattering at the Fermilabs Tevatron is presented.

TL;DR: In this article, the authors extracted 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 neutrinos deep-inelastic scattering experiments for $1l{Q}€2}l15{\mathrm{GeV}}^{2}{/c}€ 2}
