“…The integrated number of events in this sample is proportional to the flux as y = E HAD E ν → 0. Corrections up to order y 2 , determined from the data sample, are applied to determine the relative flux to about the 1% level. Flux is normalized using the world average ν-Fe cross section σ ν E ν = 0.677 × 10 −38 cm 2 /GeV [3]. The fast detector simulation, which takes into account acceptance and resolution effects, uses an empirically determined set of PDFs extracted by fitting the differential cross section [4].…”

Abstract. The NuTeV experiment obtained high statistics samples of neutrino and antineutrino charged current events during the 1996-1997 Fermilab fixed target run. The experiment combines sign-selected neutrino and antineutrino beams and the upgraded CCFR iron-scintillator neutrino detector. A precision continuous calibration beam was used to determine the muon and hadron energy scales to a precision of 0.7% and 0.43% respectively. The structure functions F 2 (x, Q 2 ) and xF 3 (x, Q 2 ) obtained by fitting the y-dependence of the sum and the difference of the ν and ν differential cross sections are presented.Neutrino deep inelastic scattering (DIS) provides a unique information for the structure of the proton and QCD, allowing the measurement of two structure functions (SF): F 2 (x, Q 2 ), and the parity-violating xF 3 (x, Q 2 ),which is accessible only by neutrino DIS [1]. The NuTeV experiment is a high-energy fixed target ν − Fe scattering experiment, which combines two new features: Separate high-purity neutrino and antineutrino beams, used to tag the primary lepton in charged-current interactions, and a continuous precision calibration beam, which improves the experiment's knowledge of the absolute energy scale for hadrons and muon, produced in neutrino interactions, to a precision of 0.43% and 0.7% respectively [2]. NuTeV took data during 1996-97 and collected 8.6 × 10 5 ν and 2.4 × 10 5 ν charged-current (CC) interactions that passed analysis cuts. ν-FE CHARGE CURRENT DIFFERENTIAL CROSS SECTIONThe differential cross section is determined fromwhere Φ(E) is the ν(ν) flux in energy bins. The cross section event sample is required to pass fiducial volume cuts, µ track reconstruction quality cuts, a minimum muon energy threshold E µ > 15 GeV, a minimum hadronic energy threshold E HAD > 10 GeV, and a minimum neutrino energy threshold E ν > 30 GeV. Selected events are binned in x, y, and E ν bins, and corrected for acceptance and smearing using a fast detector simulation. Q 2 > 1 GeV 2 is required to minimize the non-perturbative contribution to the cross section. NuTeV data ranges from 10 −3 to 0.95 in x, 0.05 to 0.95 in y, and from 30 GeV to 360 GeV in E ν . The flux is determined from data with E HAD < 20 GeV using the "fixed ν 0 " relative flux extraction method [1]. The integrated number of events in this sample is propor-

“…Therefore, NuTeV measures the neutrino flux from the number of charged current interactions in the detector using a low hadronic data sample. This method is referred to as "fixed-ν 0 " method [50,33] (summarized below) and it actually determines the relative flux in energy bins. The overall normalization is determined using the world average of absolute cross section measurements.…”

The parton momentum density distributions of the proton are determined from a next-to-leading order QCD analysis of structure functions measured at HERA and by fixed target experiments. Also included are data on the difference of the up and down anti-quark distributions. The uncertainties in the parton densities, structure functions and related cross sections are estimated from the experimental errors and those on the input parameters of the fit. Several QCD predictions based on the parton densities obtained from this analysis are calculated and compared to data. * email: m.botje@nikhef.nl
