Subjects

Abstract

We discuss effects induced by beyond leading order contributions to photon pair production. We point out that next to leading order contributions to the fragmentation component of the signal lead to a change in the shape of distributions. This is already mildly visible in present Tevatron data though stringent isolation criteria tend to suppress the fragmentation component considerably. We expect the effect to be experimentally confirmed in future data samples with higher statistics which would serve as a precision test for QCD., 11 pages, 5 eps figures, uses feynmf.sty

Abstract

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\

Abstract

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.

Abstract

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.

Abstract

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.

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.

36. Large- $p_T$ inclusive $\pi^0$ cross sections and next-to-leading-order QCD predictions.

Abstract

We review the phenomenology of $\pi^0$ production at large transverse momentum in proton-induced collisions. Uncertainties in the next-to-leading-order predictions of Quantum Chromodynamics are discussed. The comparison with data reveals that the disagreement between theory and experiment lies essentially in an overall normalization factor. The situation for $\pi^0$ production is contrasted with that of prompt-photon production in hadronic collisions. [ABSTRACT FROM AUTHOR]

Abstract

The charged-particle multiplicity distribution in decays is determined from data collected at the e+e- storage ring PEP. The one-, three-, and five-charged-particle inclusive branching fractions are (86 ± 2)%, (14 ± 2)%, and < 0.5%, respectively. © 1982 The American Physical Society.

Abstract

Our final results of measurements at SLAC of the spin dependent asymmetry in the deep inelastic scattering of longitudinally polarized electrons by longitudinally polarized protons are presented. Data were obtained at a scattering angle of 10° and for incident energies of 16.2 and 22.7 GeV, which cover the kinematic range 0.18
