students who start their master project soon, Ph.D. students from other
of physics who wish to broaden their horizon. We will discuss the analysis
of high-mass states at the Large Hadron Collider (LHC) including top and
higgs.The BCGS intensive week aims at providing a detailed insight of an LHC
detector and the experiments that are done with them to address important
questions of fundamental physics today.

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
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
important mechanisms.
About half of the course is devoted to a hand-on project which will be
as a simulation game (planspiel). Participants will experimental data of
proton proton collisions. Starting from uncalibrated hits we will create our
algorithms and finally search for the Higgs Boson at the LHC. Students will
