Massive Tadpoles: Techniques and Applications

A brief discussion of massive tadpole diagrams and their phenomenological consequences is presented. This includes predictions of the ρ parameter and, as a consequence, the mass of the W boson, implications on the charm and bottom quark masses from the moments, i.e. the derivatives of the current correlators, and the Higgs boson decay rate. A fairly consistent picture emerges, with mc(3GeV)=0.986±0.013GeV and mb(mb)=3.610±0.016GeV. Furthermore, fairly stringent predictions for the Higgs decay rate into photons and gluons are obtained, which will be interesting in increasingly precise experiments.
