Tests of Quantum Chromodynamics in Exclusive E+e-and Ye Processes*

One of the most, important area.s of investigation in quantum chromodynamics are few-hod3, exclusive reactions initiated by electromagnetic initial states. such as e'e-i HH t+tt-> + ?H. and the two-photon processes 77-+ Hfi shown in Fig. 1. The simplicity. of the photon's couplings to the quark currents and the a.bsence of initial state hadronic interactions allows one to st,ud>. the process of...

Correlations Measured in 3 He ( e , e ′ pp ) n

Tensor correlations measured in 3He(e,e' pp)n.

We have measured the 3He(e,e' pp)n reaction at an incident energy of 4.7 GeV over a wide kinematic range. We identified spectator correlated pp and pn nucleon pairs by using kinematic cuts and measured their relative and total momentum distributions. This is the first measurement of the ratio of pp to pn pairs as a function of pair total momentum p(tot). For pair relative momenta between 0.3 an...

The Angular Dependence of 16 O ( e , e ′ K + ) 16 Λ N and H ( e , e ′ K + ) Λ ( Proposal to JLab PAC - 31 ) E . Cisbani

In all Jlab hypernuclear electroproduction experiments already performed (E89-009, E94107, E01-011) or approved (E05-015) the K mesons are detected at very small (few degrees) laboratory scattering angels (measured with respect to virtual photon momentum). This region of kaon scattering angles is not covered, unfortunately, by recent photoand electroproduction data on the elementary production ...

Pertinence des Résultats de Recherche de Services Web E-Learning

Résumé. Le nombre de plateformes e-learning à base de services web est de plus en plus croissant. Ces plateformes sont de différents fournisseurs et de différentes caractéristiques et fonctionnalités. Par conséquent, leur découverte devient un défi très important. Les critères de choix et de sélection d’un service d’une plateforme e-learning dépendent, généralement, des contraintes pédagogiques...
