- Abstract
Updated results from the appearance searches for nu(mu) --> nu(tau) and nu(e) --> nu(tau) oscillations in the full NOMAD data sample are reported. The increased data and the use of more refined kinematic schemes for the nu(tau) CC selection allow a significant improvement of the overall sensitivity. The "blind analysis" of both the deep-inelastic and the low multiplicity samples yields no evidence for an oscillation signal. In the two-family oscillation scenario, this sets a 90% C.L. region in the sin(2)2 theta(mu tau) - Delta m(2) plane which includes sin(2)2 theta(mu tau) < 4.4 X 10(-4) at large Delta m(2) and Delta m(2) < 0.8 eV(2)/c(4) at sin(2)2 theta(mu tau) = 1. The corresponding contour in the nu(e) --> nu(tau) oscillation hypothesis results in sin(2)2 theta(e tau) < 2.2 X 10(-2) at large Delta m(2) and Delta m(2) < 6.5 eV(2)/c(4) at sin(2)2 theta(e tau) = 1.

- Abstract
In the context of a two-flavour approximation we reinterpret the published NOMAD limit on nu(mu) --> nu(tau) oscillations in terms of nu(e) --> nu(tau) oscillations. At 90% C.L. we obtain sin2(2)theta(e tau) < 5.2 X 10(-2) for large Delta m(2), while for sin2(2)theta(e tau) = 1 the confidence region includes Delta m(2) < 11 eV(2)/c(4).

- Abstract
The NOMAD Collaboration presents a study of opposite sign dimuon events in the framework of Leading Order QCD. A total of 2714 neutrino- and 115 antineutrino-induced opposite sign dimuon events with E-mu 1, E-mu 2 > 4.5 GeV, 15 < E-nu < 300 GeV and Q(2) > 1 (GeV/c)(2) are observed in the Front-Calorimeter of NOMAD during the 1995 and 1996 runs. The analysis yields a value for the charm quark mass of m(c) = 1.3(-0.3-0.3)(+0.3+0.3) GeV/c(2) and fur the average semileptonic branching ratio of B-c = 0.095(-0.007-0.013)(+0.007+0.014). The ratio of the strange to non-strange sea in the nucleon is measured to be kappa = 0.48(-0.07-0.12)(+0.09+0.17). The measured rate of charm-induced dimuon relative to single muon, as a function of neutrino energy, is consistent with the slow rescaling hypothesis of heavy quark production.

Physics::Instrumentation and Detectors ,High Energy Physics::Experiment - Abstract
We carried out a model-independent search for light scalar or pseudoscalar particles a's (an example of which is the axion) that couple to two photons by using a photon-regeneration method at high energies allowing a substantial increase in the sensitivity to eV masses. The experimental set-up is based on elements of the CERN West Area Neutrino Facility (WANF) beam Line and the NOMAD neutrino detector. The new particles, if they exist, could be produced through the Primakoff effect in interactions of high energy photons, generated by the 450 GeV protons in the CERN SPS neutrino target, with virtual photons from the WANF horn magnetic field. The particles would penetrate the downstream shielding and would be observed in the NOMAD neutrino detector through their re-conversion into real high energy photons by interacting with the virtual photons from the magnetic field of the NOMAD dipole magnet. From the analysis of the data collected during the 1996 run with 1.08 x 10(19) protons on target, 312 candidate events with energy between 5 and 140 GeV were found. This number is in general agreement with the expectation of 272 +/- 18 background events from standard neutrino processes. A 90 % CL upper limit on the a gamma gamma-coupling g(a gamma gamma) < 1.5 x 10(-4) GeV-1 for a masses up to 40 eV is obtained. (C) 2000 Elsevier Science B.V. All rights reserved.

High Energy Physics::Experiment - Abstract
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) the confidence region includes sin(2)2 theta(mu tau) < 1.2 X 10(-3) (a limit 3.5 times more stringent than in our previous publication), while at sin(2)2 theta(mu tau) = 1 the confidence region includes Delta m(2) < 1.2 eV(2)/c(4).

- Abstract
A search was made for a new light gauge boson X which might be produced in pi(0) -->, gamma + X decay from neutral pions generated by 450 GeV protons in the CERN SPS neutrino target. The X's would penetrate the downstream shielding and be observed in the NOMAD detector via the Primakoff effect, in the process of X --> pi(0) conversion in the external Coulomb field of a nucleus. With 1.45 x 10(18) protons on target, 20 candidate events with energy between 8 and 140 GeV were found from the analysis of neutrino data. This number is in agreement with the expectation of 18.1 +/- 2.8 background events from standard neutrino processes. A new 90% C.L. upper limit on the branching ratio Br(pi(0) --> Y + X)< (3.3 to 1.9)X 10(-5) for X masses ranging from 0 to 120 MeV/c(2) is obtained. (C) 1998 Elsevier Science B.V.

High Energy Physics::Experiment - Abstract
NOMAD is a neutrino oscillation experiment designed to search for v(tau) appearance in the CERN-SPS wide band v(mu) beam. Signal detection relies on the identification of I: charged current interactions using kinematic criteria. The analysis of the 1995 data sample yields no oscillation signal. Combining all studied tau decay modes, a limit of sin(2)2 theta(mu tau) < 4.2 x 10(-3) is obtained for large Delta m(2) at the 90% confidence level. (C) 1998 Elsevier Science B.V.

The NOMAD experiment is a short base-line search for v(mu) - v(tau) oscillations in the CERN neutrino beam. The v(tau)'s are searched for through their charged current interactions followed by the observation of the resulting tau(-) through its electronic, muonic or hadronic decays. These decays are recognized using kinematical criteria necessitating the use of a light target which enables the reconstruction of individual particles produced in the neutrino interactions. This paper describes the various components of the NOMAD detector: the target and muon drift chambers, the electromagnetic and hadronic calorimeters, the preshower and transition radiation detectors and the veto and trigger scintillation counters. The beam and data acquisition system are also described. The quality of the reconstruction and individual particles is demonstrated through the ability of NOMAD to observe K-s(o)'s, Lambda(o)'s and pi(0)s. Finally, the observation of tau(-) through its electronic decay being one of the most promising channels in the search, the identification of electrons in NOMAD is discussed.

Updated results from the appearance searches for $\numunutau$ and $\nuenutau$ oscillations in the full NOMAD data sample are reported. The increased data and the use of more refined kinematic schemes for the $\nutau$ CC selection allow a significant improvement of the overall sensitivity. The ``blind analysis" of both the deep-inelastic and the low multiplicity samples yields no evidence for an oscillation signal. In the two-family oscillation scenario, this sets a 90\% C.L. region in the $\sin^22\theta_{\mu\tau} - \Delta m^2$ plane which includes $\sin^22\theta_{\mu\tau}\ \ 4.4\times10^{-4}$ at large $\Delta m^2$ and $\Delta m^2 0.8$ eV$^2$/$c^4$ at $\sin^22\theta_{\mu \tau}=1$. The corresponding contour in the $\nuenutau$ oscillation hypothesis results in $\sin^22\theta_{e\tau}\ \ 2.2\times10^{-2}$ at large $\Delta m^2$ and $\Delta m^2 6.5$ eV$^2$/$c^4$ at $\sin^22\theta_{e \tau}=1$

neutrino interactions ,lambda polarization ,nucleon spin ,spin transfer ,High Energy Physics::Experiment ,Nuclear Experiment - Abstract
The polarization in ľ charged current interactions has been measured in the NOMAD experiment. The event sample (8087 reconstructed '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: Px(xF0)=0.09ą0.06(stat)ą0.03(sys). These results provide a test of different models describing the nucleon spin composition and the spin transfer mechanisms. A significant transverse polarization (in the direction orthogonal to the production plane) has been observed for the first time in a neutrino experiment: Py=0.22ą0.03(stat)ą0.01(sys) . The dependence of the absolute value of Py on the transverse momentum with respect to the hadronic jet direction is in qualitative agreement with the results from unpolarized hadron-hadron experiments.

High Energy Physics::Experiment ,Particle Physics - Experiment - Abstract
With additional data and improved algorithms, we have enhanced the sensitivity of our appearance search for $\numunutau$ oscillations in the NOMAD detector in the CERN-SPS wide-band neutrino beam. The search uses kinematic criteria to identify $\nutau$ 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 $\sin^22\theta_{\mu \tau} - \Delta m^2$ plane. At large $\Delta m^2$, the confidence region includes $\sin^22\theta_{\mu\tau}\

Direct photon production cross sections obtained in high statistics $\bar{p}p$ and $pp$ collisions at $\sqrt{s}=24.3$ GeV at the CERN SPS are used in a next-to-leading order QCD analysis. From the ( stat.)~\pm0.0033\,(syst.)~^{+0.0077}_{-0.0034} \,(t cross section difference $\sigma(\bar{p}p~\to~\gamma X)~-~\sigma(pp~\to~\gamma X)$ and quark distributions measured in deep inelastic scattering, a determination of the strong coupling constant, $\alpha_s$, is performed via a measurement of \ms. This measurement yields a value \ms\ = $210 \pm 22 \,(stat.) \pm 44 \,(syst.) ^{+105}_{-36} \,(theo.)$ MeV. The corresponding value of $\alpha_s$ expressed at $M^2_Z$ is $\alpha_s(M^2_Z)=0.1112~\pm0.0016\

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_muN and anti nu_muN charged current events over the Q^2 range from 1 to 100 GeV^2. 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.

neutrino oscillations ,High Energy Physics::Experiment - Abstract
With additional data and improved algorithms, we have enhanced the sensitivity of our appearance sear for nu_mu to 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 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 2theta_mu tau-Delta m^2 plane. At large Delta m^2, the confidence region includes sin^2 theta_micro thau

With additional data and improved algorithms, we have enhanced the sensitivity of our appearance search for $\numunutau$ oscillations in the NOMAD detector in the CERN-SPS wide-band neutrino beam. The search uses kinematic criteria to identify $\nutau$ 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 $\sin^22\theta_{\mu \tau} - \Delta m^2$ plane. At large $\Delta m^2$, the confidence region includes $\sin^22\theta_{\mu\tau}\ \ 1.2\times10^{-3}$ (a limit 3.5 times more stringent than in our previous publication), while at $\sin^22\theta_{\mu \tau}=1$, the confidence region includes $\Delta m^2 1.2$ eV$^2$/$c^4$.

By focusing on the notion of electronic document, we differentiate two evolutions which are useful to distinct titles: on the one hand are the documents, which have value of reference. Its administrator will take care to preserve its integrity and its context of production which is strongly significant. On the other hand are resources, evolutionary elements by nature, which the user must be able to appropriate and who must thus be placed at the disposal so that the production is erased, to focus on a logic of exploitation and service.

NOMAD is a neutrino oscillation experiment designed to search for $\nu_\tau$ appearance in the CERN-SPS wide band $\nu_\mu$ beam. Signal detection relies on the identification of $\nu_\tau$ charge d current interactions using kinematic criteria. The analysis of the 1995 data sample yields no oscillation signal. Combining all studied $\tau$ decay modes, a limit of $\sin^22\theta_{\mu \tau}~< ~4.2\times10^{-3}$ is obtained for large $\Delta m^2$ at the 90\% confidence level.

The NOMAD experiment is a short base-line search for $\nu_{\mu}\rightarrow \nu_{\tau}$ oscillations in the CERN neutrino beam. The $\nu_{\tau}$'s are searched for through their charged-current interactions followed by the observation of the resulting $\tau^{-}$ through its electronic, muonic or hadronic decays. These decays are recognized using kinematical criteria necessitating the use of a light target which enables the reconstruction of individual particles produced in the neutrino interactions. This paper describes the various components of the NOMAD detector: the target and muon drift chambers, the electromagnetic and hadronic calorimeters, the preshower and transition radiation detectors, and the veto and trigger scintillation counters. The beam and data acquisition system are also described. The quality of the reconstruction of individual particles is demonstrated through the ability of NOMAD to observe K$^0_{\rm s}$'s, $\Lambda^0$'s and $\pi^0$'s. Finally, the observation of $\tau^{-}$ through its electronic decay being one of the most promising channels in the search, the identification of electrons in NOMAD is discussed.

Physics::Instrumentation and Detectors ,High Energy Physics::Experiment ,Nuclear Experiment - Abstract
A search was made for a new light gauge boson X which might be produced in pi^0--gamma + X decay from neutral pions generated by 450-GeV protons in the CERN SPS neutrino target. Th e X's would penetrate the downstream shielding and be observed in the NOMAD detector via the Primakoff effect, in the process of X --pi^0 conversion in the external Coulomb field of a nucleus. With 1.45x10^18 protons on target, 20 candidate events with energy between 8 and 140 GeV were found from the analysis of neutrino data.This number is in agreement with the e xpectation of 18.1?2.8 background events from standard neutrino processes.A new 90 % ~C.L. upper limit on the branching ratio Br(?0?? + X) (3.3~to~1.9)?10-5 for X masses ranging from 0 to 120 MeV/c2 is obtained.
