Theoretical analysis of decays

Theoretical Analysis of ¯B → D ∗ ∗ π Decays

The decays ¯ B → D * * π, where D * * is a narrow p-wave charm resonance, are investigated in the context of a generalized factorization hypothesis, including the leading nonfactorizable corrections. The decay rates for these processes are related to the corresponding semileptonic rates at maximum recoil. It is pointed out that the current data on the branching ratio for the decay B − → D * 0 2...

Theoretical Review of Radiative Rare B Decays

A status report on the theory of radiative rare B decays in the standard model is presented, with focus on inclusive decays B → X(s,d) γ and exclusive decays B → (K, ω, ρ) γ. CP asymmetries are also briefly discussed.

Theoretical Aspects of Rare Kaon Decays A

Most of the analytic approaches which are used at present to understand Kaon decays, get their inspiration from QCD in the limit of a large number of colours Nc. After a general overview, we illustrate this with a recent application to the evaluation of the process KL → µ + µ − in the Standard Model.
