What does one need to know to analyse LHC data? While following these lines, particular emphasis is given to scientific and technical requirements of LHC detectors physics of tracking and energy detectors theoretical background of LHC physics (Standard Model + Higgs physics) experimental methods to address these physics questions, including neural net applications Of course, not all topics can be addressed to depth within one week. Thus an effort is made that students will receive an overview and understand the most important mechanisms. About half of the course is devoted to a handon project which will be organized as a simulation game (planspiel). Participants will experimental data of proton proton collisions. Starting from uncalibrated hits we will create our own algorithms and finally search for the Higgs Boson at the LHC. Students will learn several aspects of C++ and its applications in high energy physics.
