ATLAS: Fourth Generation, Event Shapes, Monte Carlo and SCT Detector

Abstract

Continuation of the Search for quarks of a forth generation, of the examination of rare processes (diboson processes, t-anti-t + vectorboson), das Studium von "Fat Jets" by Event Shape variables, Monte Carlo tuning by ATLAS data, and of the maintenance of the inner detector (initally still Pixel, later SCT), and preparation of the SCT detector extension.
