QCD Factors a1 and a2 Beyond Leading Logarithms Versus Factorization in Non-Leptonic Heavy Meson Decays

A. J. Buras

We calculate the QCD factors $a_{1}$ and $a_{2}$ , entering the tests of factorization in non-leptonic heavy meson decays, beyond the leading logarithmic approximation in three renormal…

Limitations in Measuring the Angle $β$ by Using $S U (3)$ Relations for $B$ -Meson Decay-Amplitudes

A. J. Buras, R. Fleischer

Flavour $S U (3)$ symmetry of strong interactions and certain dynamical assumptions have been used in a series of recent publications to extract weak CKM phases from $B$ -decays into…

Towards Precise Determinations of the CKM Matrix without Hadronic Uncertainties

A. J. Buras

We illustrate how the measurements of the CP asymmetries in $B_{d, s}^{0}$ -decays together with a measurement of $B r (K_{L} \to π^{\circ} ν ν ˉ)$ or $B r (K^{+} \to π^{+} ν ν ˉ)$ and the known val…

Parity Violating Longitudinal Muon Polarization in $K^{+} \to π^{+} μ^{+} μ^{-}$ Beyond Leading Logarithms

G. Buchalla, A. J. Buras

We generalize the existing analyses of the parity violating muon polarization asymmetry $Δ_{L R}$ in $K^{+} \to π^{+} μ^{+} μ^{-}$ beyond the leading logarithmic approximation. The inclusion of…

CP Violation: Present and Future

A. J. Buras

We review the present status of CP violation in the standard model. Subsequently we make an excursion in the future in order to see what we could expect in this field in this and t…

Precise Determinations of the CKM Matrix from CP-Asymmetries in B-Decays and K_L --> π^0 ν\barν

A. J. Buras

We point out that the measurements of the CP asymmetries in neutral B-decays together with a measurement of $B r (K_{L} \to π^{\circ} ν ν ˉ)$ and the known value of $∣ V_{u s} ∣$ can…

$sin 2 β$ from $K \to π ν ν ˉ$

Gerhard Buchalla, Andrzej J. Buras

We point out that the measurement of just the two branching fractions \linebreak $B (K^{+} \to π^{+} ν ν ˉ)$ and $B (K_{L} \to π^{0} ν ν ˉ)$ can in a theoretically clean manner determine $\sin 2…

Waiting for the Top Quark Mass, K^+ --> π^+ ν\barν, B_s^0-\bar{B}_s^0 Mixing and CP Asymmetries in B-Decays

A. J. Buras, M. E. Lautenbacher, G. Ostermaier

Anticipating improved determinations of m_t, |V_ub/V_cb|, B_K and F_B \sqrt{B_B} in the next five years we make an excursion in the future in order to find a possible picture of th…

Direct CP Violation in K_L --> π^0 e^+e^- Beyond Leading Logarithms

A. J. Buras, M. E. Lautenbacher, M. Misiak +1

We analyze the direct CP violation in the rare decay K_L --> Pi^0 e+e- with QCD effects taken into account consistently in the next-to-leading order. We calculate the two-loop mixi…
