Weak interaction: Reassembly of particules

The Standard Model interprets the weak interaction, e.g. neutron beta decay, to be a short-range field carried by the W and Z bosons. In that interpretation the short range arises because of the heavy mass of the W and Z bosons. This paper reconceptualises the weak interaction and the bosons. The cordus HED notation was used to work out the field structures of the bosons, giving W(r. .a.1 1.1 ....

Mise en oeuvre d'une architecture de reconnaissance de formes pour la détection de particules à partir d'images atmosphériques

The HESS experiment consists of a system of telescopes destined to observe cosmic rays.Since the project has achieved a high level of performances, a second phase of the project has beeninitiated. This implies the addition of a new telescope which is more sensitive than its predecessorsand which is capable of collecting a huge amount of images. In this context, all data collecte...

INTERACTIONS PARTICULES-MATIERE: Analyse de surface

La spectrométrie de photoélectrons induits par rayons-X (XPS) est actuellement une des techniques analytiques le plus abondamment utilisée pour fournir des informations sur la composition, la structure électronique et les liaisons chimiques des solides. Une analyse précise implique une mesure précise des pics de photoélectrons mais ces pics sont superposés à un fond continu en raison des diffus...

The QCD dipole picture allows to build an unified theoretical description-based on BFKL dynamics-of the total and diffractive nucleon structure functions measured at HERA. We use a four parameter fit to describe the 1994 H1 proton structure function F 2 data in the low x, moderate Q 2 range. The diffractive dissociation processes are discussed within the same framework, and a 6 parameter fit of...
