High precision tests of the Standard Model of Particle Physics, in particular tests of the CKM mechanism as tool to search for New Physics. A ideal laboratory to perform this kind of tests is the B meson system, which shows, according to the Standard Modell, large CP violating effects. Our group participates in the BABAR experiment at SLAC (Stanford) and at the LHCb experiment at the Large Hadron Collider (LHC) at CERN.
A second research field is the development and the construction of large area gaseous tracking detectors, including the development of the necessary readout and DAQ electronics.

	LHCb is one of the 4 experiments currently being built at the LHC. The experiment will start data-taking mid 2008. Our Heidelberg goup is involved in the construction of the Outer Tracker a part of LHCb's main tracking system. The sub-detector is currently being finished and commssioned. Members of the Heidelberg group are responsible for the commissioning of the readout and detector control as well as for the drift chamber module commissioning. Our group is also responisble for the alignment of the detector elements and for the developement of tracking algortithms (here we specialize on fast algorithms for the use in the L1 trigger). A detailed description of our group activities can be found here (more information on LHCb@HD)

	BABAR is a successful running experiment and it has meanwhile collected nearly 500 million B meson pairs. Beside this large number of B meson pairs the detector has recorded as many tau pairs. The Heidelberg groups is focusing on the analysis of tau decays into hadrons with netto strangeness as they allow the determination of the CKM matrix element Vus. We also participate in the study of semi-leptonic B meson decays. Our main interest here is the reconstruction of exclusive B decays. More Information on BABAR@HD.
