Two loop virtual corrections to $b \to (d, s) ℓ^{+} ℓ^{-}$ and $c \to u ℓ^{+} ℓ^{-}$ for arbitrary momentum transfer

Stefan de Boer

Non-factorizable two loop corrections to heavy to light flavor changing neutral current transitions due to matrix elements of current-current operators are calculated analytically…

Rare radiative charm decays within the standard model and beyond

Stefan de Boer, Gudrun Hiller

We present standard model (SM) estimates for exclusive $c \to u γ$ processes in heavy quark and hybrid frameworks. Measured branching ratios $B (D^{0} \to (ϕ, K ˉ^{* 0}) γ)$ …

Higher-order Wilson coefficients for c $\to$ u transitions in the Standard Model

Stefan de Boer, Bastian Müller, Dirk Seidel

The standard theoretical framework to deal with weak decays of heavy mesons is the so-called weak effective Hamiltonian. It involves the short-distance Wilson coefficients, which d…
