Electromagnetic tails of $B$ -meson light-cone distribution amplitudes

Max Ferré, Matthias Neubert

We investigate electromagnetic corrections to the $B$ -meson decay constant and light-cone distribution amplitudes (LCDAs) within the framework of heavy-quark effective theory. The…

QED Corrections to $B^{-} \to τ^{-} ν ˉ_{τ}$

Claudia Cornella, Max Ferré, Matthias König +1

Using a sequence of effective field theories (EFTs), we calculate the rate for the leptonic decay $B^{-} \to τ^{-} ν ˉ_{τ} (γ)$ including real and virtual QED corrections, with a cut $E_{\…

The Simplest B Decay, Precisely

Claudia Cornella, Max Ferré, Matthias König +1

We derive the QCD $\times$ QED factorization theorem governing the leptonic decay $B^{-} \to μ^{-} ν ˉ_{μ} (γ)$ at all orders in $α_{s}$ and $α$ . Electromagnetic corrections to this decay prob…
