Mesure DE La Section Efficace DE Production DE Paires DE Quarks Top Dans L'Etat Final DI-Electron Avec Les Donnees Collectees Par L'Experience d0 AU Runiia

Description: The top quark has been discovered in 1995 by CDF and D0 collaborations in proton-antiproton collisions at the Tevatron. The amount of data recorded by both experiments makes it possible to accurately measure the properties of this very massive quark. This thesis is devoted to the measurement of the top pair production cross-section via the strong interaction, in a final state composed of two electrons, two particle jets and missing transverse energy. It is based on a 1 fb{sup -1} data set colle… more

Learner use of French second-person pronouns in synchronous electronic communication.

Description: This study analyzes students' use of the French second-person pronouns tu (T) and vous (V) in small-group (2-3 students) inter-learner online chat sessions. The influence of internal linguistic factors (i.e., turn type and morphosyntactic environment) on learners' appropriate vs. inappropriate use of these pronouns is considered. The study also investigates the influence of Instructional Level on tu-vous use and the extent to which students from different instructional levels provide various ty… more

Study of correlations between photoproduced pairs of charmed particles at Experiment E831/FOCUS

Description: The authors present the study of the charm-pair correlations produced in photon-nucleon interactions at <E{sub {gamma}}> = 175 GeV/c, by the Fermilab fixed target experiment E831/FOCUS. The E831/FOCUS experiment produced and reconstructed over one million charm particles. This high statistics allows the reconstruction of more than 7000 charm-pair mesons D{bar D}, 10 times the statistic of former experiments, and also allows to get, for the first time, about 600 totally reconstructed charm… more
