These lectures do not at all provide a general review of this rapidly growing field. Instead a rather detailed account is presented of a number of the most elementary aspects.

The hot electroweak potential for small Higgs field values is argued to obtain contributions from a fluctuating gauge field background leading to confinement. The destabilization of F 2 = 0 and the crossover are discussed in our phenomenological approach, also based on lattice data.

The decays B+ → D∗+ s γ and B+ → D∗+γ can be used for an extraction of |Vub|. When the b and c quarks are nearly degenerate the rate for these modes can be determined in terms of other observed rates, namely BB mixing and D → Dγ decay. To this end we introduce a novel application of heavy quark and flavor symmetries. Although somewhat unrealistic, this limit provides us with a first estimate of...
