Leptoquarks meet $ε^{'} / ε$ and rare Kaon processes

Christoph Bobeth, Andrzej J. Buras

We analyse for the first time the CP violating ratio $ε^{'} / ε$ in $K \to π π$ decays in leptoquark (LQ) models. Assuming a mass gap to the electroweak (EW) scale, th…

Enhanced electromagnetic correction to the rare $B$ -meson decay $B_{s, d} \to μ^{+} μ^{-}$

Martin Beneke, Christoph Bobeth, Robert Szafron

We investigate electromagnetic corrections to the rare $B$ -meson leptonic decay $B_{s, d} \to μ^{+} μ^{-}$ from scales below the bottom-quark mass $m_{b}$ . Contrary to QCD effects, which a…

Long-distance effects in $B \to K^{*} ℓℓ$ from Analyticity

Christoph Bobeth, Marcin Chrzaszcz, Danny van Dyk +1

We discuss a novel approach to systematically determine the long-distance contribution to $B \to K^{*} ℓℓ$ decays in the kinematic region where the dilepton invariant mass is bel…

Yukawa enhancement of $Z$ -mediated New Physics in $Δ S = 2$ and $Δ B = 2$ Processes

Christoph Bobeth, Andrzej J. Buras, Alejandro Celis +1

We discuss Yukawa-enhanced contributions from $Z$ -mediated new physics to down-type quark $Δ F = 2$ processes in the framework of the standard model gauge-invariant effective theory (…
