Non-Leptonic Two-Body B Decays Beyond Factorization

Andrzej J. Buras, Luca Silvestrini

We present a general scheme and scale independent parameterization of two-body non-leptonic B decay amplitudes which includes perturbative QCD corrections as well as final state in…

Upper Bounds on $K \to π ν ν ˉ$ and $K_{L} \to π^{0} e^{+} e^{-}$ from $ε^{'} / ε$ and $K_{L} \to μ^{+} μ^{-}$

Andrzej J. Buras, Luca Silvestrini

We analyze rare kaon decays in models in which the dominant new effect is an enhanced $s ˉ d Z$ vertex $Z_{d s}$ . We point out that in spite of large theoretical uncertainties th…

A General Analysis of $γ$ Determinations from $B \to π K$ Decays

Andrzej J. Buras, Robert Fleischer

We present a general parametrization of $B^{\pm} \to π^{\pm} K, π^{0} K^{\pm}$ and $B_{d} \to π^{0} K, π^{\mp} K^{\pm}$ decays, taking into account both electroweak penguin and rescattering effects. Th…

Weak Hamiltonian, CP Violation and Rare Decays

Andrzej J. Buras

These lectures describe in detail the effective Hamiltonians for weak decays of mesons constructed by means of the operator product expansion and the renormalization group method.…

Generalized Factorization in Non-leptonic Two-Body B-Decays: a Critical Look

A. J. Buras, L. Silvestrini

We reanalyze critically the generalized factorization hypothesis in non-leptonic two-body B-decays discussed recently by several authors. In particular we address the determination…
