R\u00e9sum\u00e9<\/p>

Ces notes sont une introduction \u00e0 l’application de l’\u00e9lectrodynamique quantique (QED) et de la chromodynamiques quantique (QCD) aux r\u00e9actions de diffusion \u00e0 hautes \u00e9nergies. Le premier th\u00e8me abord\u00e9 est celui des divergences ultraviolettes et de la renormalisation \u00e0 une boucle, avec comme cons\u00e9quence pour QCD la libert\u00e9 asymptotique. Le deuxi\u00e8me th\u00e8me est celui des divergences infrarouges et colin\u00e9aires qui dans QCD sont trait\u00e9es dans le cadre du mod\u00e8le des partons avec l’introduction des fonctions de structure d’un hadron. On montre comment la violation d’invariance d’\u00e9chelle est engendr\u00e9e par les corrections radiatives et on discute le th\u00e9or\u00e8me de factorisation dans l’approximation \u00e0 une boucle. Plusieurs applications ph\u00e9nom\u00e9nologiques dans les collisions e<\/span>+<\/span><\/span>e<\/span>\u2212<\/span><\/span><\/span><\/span><\/span>, e<\/span><\/span>p<\/span><\/span><\/span><\/span> et p<\/span><\/span>p<\/span><\/span><\/span><\/span> sont pr\u00e9sent\u00e9es, avec notamment la production de bosons de jauge, de gerbes hadroniques (“jets”) et de particules \u00e0 grande impulsion transverse dans les collisionneurs hadroniques. Dans tous les cas les pr\u00e9dictions sont confront\u00e9s avec les r\u00e9sultats exp\u00e9rimentaux r\u00e9cents.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

Summary<\/p>

The unified model of electroweak interactions (Glashow-Weinberg-Salam model) is constructed step by step. As an application, the phenomenology of neutrino mixing, in the framework of the three-family model, is dicussed in detail. Numerous formulae for appearance or disappearance of neutrinos in vacuum or in matter are derived. These notes shoud provide a self-contained introduction to the GWS model and to neutrino mixing and oscillations. Recent experimental results on neutrino oscillations are briefly reviewed.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
