Search for nu(mu) -> nu(e) oscillations in the NOMAD experiment
2003
We present the results of a search for nu(mu) --> nu(e) oscillations in the NOMAD experiment at CERN. The experiment looked for the appearance of nu(e) in a predominantly nu(mu) wide-band neutrino beam at the CERN SPS. No evidence for oscillations was found. The 90% confidence limits obtained are Deltam(2) < 0.4 eV(2) for maximal mixing and sin(2) (20) < 1.4 x 10(-3) for large Deltam(2). This result excludes the LSND allowed region of oscillation parameters with Deltam(2) greater than or similar to 10 eV(2).
Measurement of the Lambda polarization in nu(mu) charged current interactions in the NOMAD experiment
2000
The Lambda polarization in upsilon (mu) charged current interactions has been measured in the NOMAD experiment. The event sample (8087 reconstructed Lambda 's) is more than an order of magnitude larger than that of previous bubble chamber experiments, while the quality of event reconstruction is comparable. We observe negative polarization along the W-boson direction which is enhanced in the target fragmentation region: P-x(x(F) 0) = -0.09 +/- 0.06(stat) +/- 0.03(sys). These results provide a test of different models describing the nucleon spin composition and the spin transfer mechanisms. A significant transverse polarization tin the direction orthogonal to the Lambda production plane! has…
A study of backward going protons and negative pions in Numu CC interactions with the NOMAD detector
2001
Backward proton and π− production has been studied in νμCC interactions with carbon nuclei. Detailed analyses of the momentum distributions, of the production rates, and of the general features of events with a backward going particle, have been carried out in order to understand the mechanism producing these particles. The backward proton data have been compared with the predictions of the reinteraction and the short range correlation models.
Measurement of the Antilambda Polarisation in Nu(mu) Charged Current Interactions in the NOMAD Experiment
2001
We present a measurement of the polarization of Antilambda hyperons produced in nu_mu charged current interactions. The full data sample from the NOMAD experiment has been analyzed using the same V0 identification procedure and analysis method reported in a previous paper for the case of Lambda hyperons. The Antilambda polarization has been measured for the first time in a neutrino experiment. The polarization vector is found to be compatible with zero.

2008
We present a measurement of the muon neutrino-nucleon inclusive charged current cross section, off an isoscalar target, in the neutrino energy range 2.5 <= E-v <= 40 GeV. The significance of this measurement is its precision, +/- 4% in 2.5 <= E-v <= 10 GeV, and +/- 2.6% in 10 <= E-v <= 40 GeV regions, where significant uncertainties in previous experiments still exist, and its importance to the current and proposed long baseline neutrino oscillation experiments.
Final NOMAD results on nu(mu) -> nu(tau) and nu(e) -> nu(tau) oscillations including a new search for nu(tau) appearance using hadronic tau decays
2001
Results from the v, appearance search in a neutrino beam using the full NOMAD data sample are reported. A new analysis unifies all the hadronic tau decays, significantly improving the overall sensitivity of the experiment to oscillations. The 'blind analysis' of all topologies yields no evidence for an oscillation signal. In the two-family oscillation scenario, this sets a 90% CL allowed region in the sin(2)2 theta (mu tau)-Deltam(2) plane which includes sin(2)2 theta (mu tau) nu (tau) oscillation hypothesis results in sin(2) 2 theta (l tau) < 1.5 x 10(-2) at large Deltam(2) and Deltam(2) < 5.9 eV(2)/c(4) at sin(2) 2 theta (l tau) = 1. We also derive limits on effective couplings of the tau…
Precision measurement of scaled momentum, charge multiplicity, and thrust in nu N-mu and (nu)over-bar(mu)N interactions
1999
We report the first precision measurements of the scaled momentum, the charge multiplicity, and the thrust of hadronic jets in the Breit frame in Deep Inelastic Scattering nu(mu)N and charged cur rent events over the Q(2) range from 1 to 100 GeV2. The neutrino data, obtained in the NOMAD experiment at the CERN SPS, extend the Q(2)-evolution of these parameters by two orders of magnitude, and with commensurate precision, when compared to those reported by the ep and e(+)e(-) experiments
A more sensitive search for nu(mu) -> nu(tau) oscillations in NOMAD
1999
With additional data and improved algorithms, we have enhanced the sensitivity of our appearance search for nu(mu) --> nu(tau) oscillations in the NOMAD detector in the CERN-SPS wide-band neutrino beam. The search uses kinematic criteria to identify nu(tau) charged current interactions followed by decay of the tau(-) to one of several decay modes. Our 'blind'' analyses of deep-inelastic scattering data taken in 1996 and 1997, combined with consistent reanalyses of previously reported 1995 data, yield no oscillation signal. For the two-family oscillation scenario, we present the contour outlining a 90% C.L. confidence region in the sin(2)2 theta(mu tau) - Delta m(2) plane. At large Delta m(2…
Limit on nu(e) -> nu(tau) oscillations from the NOMAD experiment
2000
In the context of a two-flavour approximation we reinterpret the published NOMAD limit on νμ→ντ oscillations in terms of νe→ντ oscillations. At 90% C.L. we obtain Full-size image (<1 K) for large Δm2, while for sin22θeτ=1 the confidence region includes Δm2<11 eV2/c4.
