TTP04-14 Multiloop Tadpoles

We present a semi-numerical approach which allows the calculation of four-loop tadpole diagrams. The method is introduced by presenting the results for a scalar four-loop diagram. Finally, the application of the method to the calculation of a physical quantity like the four-loop vacuum polarization in QCD is discussed.
