Un multilinguisme en construction : l’éveil de la conscience métalinguistique

On se propose, dans la présente contribution, de mettre en évidence les traces de l’émergence, chez l’enfant d’âge scolaire, de la conscience métalinguistique, à travers diverses activités telles que le contact avec des systèmes linguistiques diversifiés ou l’observation concrète de certains phénomènes langagiers.Seront ainsi analysés des exemples d’interactions menées dans la classe à propos de notions telles que la temporalité, l’accent ou l’ordre des mots. On s’attachera à mettre en évidence ce qui manifeste, chez les sujets étudiés, la prise de conscience progressive de l’univers du langage dans certaines de ses caractéristiques jugées pertinentes pour des apprentissages futurs.In this article, we retrace the emergence of metalinguistic awareness in school children through the examination of language contact and other relevant phenomena. To this end, we analyse instances of classroom interaction and attempt to identify the developing linguistic awareness of these subjects for temporality. Word order and accent

Open charm production at HERA

Inclusive charm meson production cross sections in the deep inelastic scattering and photoproduction regimes are compared with QCD leading and next-to-leading (NLO) calculations. The NLO predictions are significantly below the data in some parts of the measured kinematic range. Angular distributions of dijet events with charm show clear evidence for the existence of charm originating from the incoming photon. The charm fragmentation function is measured for the first time at HERA. Various fragmentation ratios and the fragmentation fractions of the low-lying charm hadrons are determined and compared to previous e+e- results.Comment: 6 pages, 7 figures, to appear in the proceedings of the International Conference on the Structure and Interactions of the Photon, Frascati (Italy), 7-11 April 200

Latest Highlights from the H1 Collaboration

Recent data obtained in ep collisions at HERA by the H1 collaboration are presented: searches for new phenomena beyond the Standard Model, measurement of the inclusive neutral and charged current cross sections and of the proton structure function, determination of the gluon density in the proton and photon from jet productions, measurement and interpretation of event shapes in the current region of the Breit frame, test of the parton evolution at low x and of the diffractive production mechanism.Comment: 17 pages, 21 figures, plenary talk at 7th International Workshop on Deep Inelastic Scattering and QCD, Berlin-Zeuthen (Germany), April 199

The H1 Forward Proton Spectrometer at HERA

The forward proton spectrometer is part of the H1 detector at the HERA collider. Protons with energies above 500 GeV and polar angles below 1 mrad can be detected by this spectrometer. The main detector components are scintillating fiber detectors read out by position-sensitive photo-multipliers. These detectors are housed in so-called Roman Pots which allow them to be moved close to the circulating proton beam. Four Roman Pot stations are located at distances between 60 m and 90 m from the interaction point.Comment: 20 pages, 10 figures, submitted to Nucl.Instr.and Method

Theoretical constraints on new generations with and without Quarks or Neutrinos

We consider large classes of chiral extensions of the Standard Model, including new quark generations that do not involve additional neutrinos as well as lepton generations without quarks. An analysis of renormalization flows of Yukawa and quartic scalar couplings reveals that additional quarks are not compatible with a scenario of grand unification without violating the strong bounds from direct and Higgs searches at colliders. Constraints from direct searches, electroweak precision observables, and Higgs physics, together with the assumption that additional new physics beyond the extended chiral field content should enter significantly above the TeV scale, allows us to make predictions for searches at the LHC
