Resonances gone topsy turvy - the charm of QCD or new physics in $b \to s ℓ^{+} ℓ^{-}$ ?

James Lyon, Roman Zwicky

We investigate the interference pattern of the charm-resonances $Ψ (3370, 4040, 4160, 4415)$ with the electroweak penguin operator $O_{9}$ in the branching fraction of $B^{+} \to K^{+} μμ$ . Fo…

Heavy-to-light chromomagentic matrix element

Maria Dimou, James Lyon, Roman Zwicky

We report the computation of the matrix element of the chromomagnetic operator of the flavour changing neutral current (FCNC)-type between a $B$ - or $D$ -meson state and a light had…

Isospin asymmetries in $B \to (K^{*}, ρ) γ / l^{+} l^{-}$ and $B \to K l^{+} l^{-}$ in and beyond the Standard Model

James Lyon, Roman Zwicky

We compute the isospin asymmetries in $B \to (K^{*}, ρ) γ$ and $B \to (K, K^{*}, ρ) l^{+} l^{-}$ for low lepton pair invariant mass $q^{2}$ , within the Standard Model (SM) and beyond the SM (BSM)…

Exclusive Chromomagnetism in heavy-to-light FCNCs

Maria Dimou, James Lyon, Roman Zwicky

We compute matrix elements of the chromomagnetic operator, often denoted by $O_{8}$ , between $B / D$ -states and light mesons plus an off-shell photon by employing the method of…
