$K \to π ν ν ˉ$ : A Model Independent Analysis and Supersymmetry

A. J. Buras, A. Romanino, L. Silvestrini

We present a model independent analysis of new-physics contributions to the decays K^+ \to π^+ ν\bar νand K_L \to π^0 ν\bar ν. We parameterize the effects of new physics in these d…

CKM Matrix: Present and Future

Andrzej J. Buras

We review the present status of the CKM matrix and we offer some visions of its future. After a brief presentation of the theoretical framework for weak decays we discuss the follo…

Penguin Topologies, Rescattering Effects and Penguin Hunting with $B_{u, d} \to K K ˉ$ and $B^{\pm} \to π^{\pm} K$

Andrzej J. Buras, Robert Fleischer, Thomas Mannel

In the recent literature, constraints on the CKM angle $γ$ arising from the branching ratios for $B^{\pm} \to π^{\pm} K$ and $B_{d} \to π^{\mp} K^{\pm}$ decays received a lot of attention. An im…

Next-To-Leading-Order Matching for the Magnetic Photon-Penguin Operator in the $B \to X_{s} γ$ Decay

A. J. Buras, A. Kwiatkowski, N. Pott

The initial condition at the matching scale $μ_{W} = O (M_{W})$ for the Wilson coefficient of the magnetic photon-penguin operator in the decay $B \to X_{s} γ$ is calculated in the next-to…

Two-Loop Large- $m_{t}$ Electroweak Corrections to $K \to π ν ν ˉ$ for Arbitrary Higgs Boson Mass

Gerhard Buchalla, Andrzej J. Buras

We consider for the first time the leading large top mass corrections, arising at higher order in electroweak interactions, to the rare decays $K \to π ν ν ˉ$ and the related modes $…

On the Scale Uncertainties in the $B \to X_{s} γ$ Decay

Andrzej J. Buras, Axel Kwiatkowski, Nicolas Pott

We analyze the theoretical uncertainties in $B r (B \to X_{s} γ)$ due to the choice of the high energy matching scale $μ_W=\ord(\mw)$ and the scale $μ_{t}$ at which the running top quark m…

Quark mixing, CP violation and rare decays after the top quark discovery

Andrzej J. Buras, Robert Fleischer

We review the highlights of quark mixing, particle-antiparticle mixing, CP violation and rare K- and B-decays in the Standard Model. The top quark discovery, the precise measuremen…
