Identifiants et référentiels dans l'archive ouverte HAL

National audienceL'archive ouverte HAL (infrastructure nationale) est destinée au dépôt et à la diffusion de documents scientifiques. Dès l'origine et encore plus depuis la v3, les métadonnées des documents sont associées à des référentiels : Auteurs, Structures, Financeurs, etc. Nous présenterons ces différents objets en développant plus précisément l'IdHAL, l'identifiant chercheur de HAL

Bilan 2011 de la plateforme ISIDORE et perspectives 2012-2015

Ce rapport vise à analyser les utilisations de la plate-forme Isidore entre le 1er mai et le 15 octobre 2011 et en nous appuyant sur les observations et les enseignements qu'il est possible d'en tirer, nous proposerons des pistes de réflexion en vue d'élaborer une feuille de route de pilotage, qui dépasse le simple cadre de l'évolution technique de la plate-forme Isidore, pour les quatre années à venir. Il s'agit de réfléchir à la place et au rôle d'Isidore dans le paysage de la recherche en sciences humaines et sociales afin d'anticiper au mieux les évolutions - toujours nécessaires pour un moteur de recherche - que cet outil d'accès unifié aux données devra recevoir dans les années qui viennent

Les braséros tripodes à Mégara Hyblaea : analyses typologiques et archéométriques

Few fire places were discovered in the houses of Megara Hyblaea. On the contrary, tripod braziers were quite numerous and their use in the kitchen seems probable. Their forms are untraditional and two very different types can be distinguished. Petrographic analyses allowed the identification of four main groups of fabrication. The majority of the ceramics studied appears to be imported, possibly from northeastern Sicily and the Aegean

The dependence of the anomalous J/psi suppression on the number of participant nucleons

The observation of an anomalous J/psi suppression in Pb-Pb collisions by the NA50 Collaboration can be considered as the most striking indication for the deconfinement of quarks and gluons at SPS energies. In this Letter, we determine the J/psi suppression pattern as a function of the forward hadronic energy E-ZDC measured in a Zero Degree Calorimeter (ZDC). The direct connection between EZDC and the geometry of the collision allows us to calculate, within a Glauber approach, the precise relation between the number of participant nucleons N-part and E-ZDC. Then, we check if the experimental data can be better explained by a sudden or a smooth onset of the anomalous J/psi suppression as a function of the number of participants.

Centrality Behaviour of J/ψ\psi Production in Na50

The J/$\psi$ production in 158 A GeV Pb-Pb interactions is studied, in the dimuon decay channel, as a function of centrality, as measured with the electromagnetic or with the very forward calorimeters. After a first sharp variation at mid centrality, both patterns continue to fall down and exhibit a curvature change at high centrality values. This trend excludes any conventional hadronic model and is in agreement with a deconfined quark-gluon phase scenario. We report also preliminary results on the measured charged multiplicity, as given by a dedicated detector.Comment: 5 pages, 7 figures (in eps) talk given at XXXI International Symposium on Multiparticle Dynamics, Sep. 1-7, 2001, Datong China URL http://ismd31.ccnu.edu.cn

Charmonium production in Pb-Pb collisions

NA50The elaboration of specific media-planning is necessary to communicate with an opinion leader. Opinion leaders in 27 product categories are selected from a 10,000 sample of French representative consumers. Magazine is the favorite media of opinion leaders; the more important is the number of product categories in which a consumer is leaders, the greater the media consumption. Leaders do not systematically prefer the Internet, their preference appears to be category specific. However, a second study conducted among 600 brand website visitors shows that brand sites represent a major information source for the leaders
