Specific three-loop contributions to $b \to s γ$ associated with the current-current operators

Christoph Greub, Hrachia M. Asatrian, Francesco Saturnino +1

We work out a specific class of three-loop diagrams (of order $α_{s}^{2}$ ) contributing to the decay amplitude for $b \to s γ$ associated with the current-current operators $O_{1}$ and $…

$b \to s ℓ^{+} ℓ^{-}$ Transitions in Two-Higgs-Doublet Models

Andreas Crivellin, Dario Müller, Christoph Wiegand

In this article we study $b \to s μ^{+} μ^{-}$ transitions and possible correlations with the anomalous magnetic moment of the muon ( $a_{μ}$ ) within two-Higgs-doublet models with generic Yu…
