Non-perturbative Effects in $B \to X_{s} l^{+} l^{-}$

Gerhard Buchalla

The rare decay $B \to X_{s} l^{+} l^{-}$ provides excellent prospects for precision tests of Standard Model flavour dynamics. The process can be computed in perturbation theory with small u…

Next-to-Leading Order QCD Corrections to the Lifetime Difference of $B_{s}$ Mesons

M. Beneke, G. Buchalla, C. Greub +2

We compute the QCD corrections to the decay rate difference in the $B_{s} - B ˉ_{s}$ system, $Δ Γ_{B_{s}}$ , in the next-to-leading logarithmic approximation using the heavy quark expansi…

The CP Conserving Contribution to $K_{L} \to π^{0} ν ν ˉ$

Gerhard Buchalla, Gino Isidori

The rare decay $K_{L} \to π^{0} ν ν ˉ$ is dominated by direct CP violation and can be computed with extraordinarily high precision. In principle also a CP conserving contribution to this…

Nonperturbative Effects in $B ˉ \to X_{s} l^{+} l^{-}$ for Large Dilepton Invariant Mass

Gerhard Buchalla, Gino Isidori

We reconsider the calculation of $O (Λ_{QC D}^{2} / m_{b}^{2})$ nonperturbative corrections to $B ˉ \to X_{s} l^{+} l^{-}$ decay. Our analysis confirms the results of Ali et al. for the dil…
