Resolving the Flavor Structure in the MFV-SMEFT

Sebastian Bruggisser, Danny van Dyk, Susanne Westhoff

We constrain the flavor structure of Wilson coefficients in the Standard Model Effective Field Theory (SMEFT) from data. In the SMEFT, new physics effects in couplings of up-type a…

Dispersion relations for $B^{-} \to ℓ^{-} ν ˉ_{ℓ} ℓ^{' -} ℓ^{' +}$ form factors

Stephan Kürten, Marvin Zanke, Bastian Kubis +1

Using dispersive methods, we study the $B \to γ^{*}$ form factors underlying the decay $B^{-} \to ℓ^{-} ν ˉ_{ℓ} ℓ^{' -} ℓ^{' +}$ . We discuss the ambiguity that arises…

Improved Theory Predictions and Global Analysis of Exclusive $b \to s μ^{+} μ^{-}$ Processes

Nico Gubernari, Méril Reboud, Danny van Dyk +1

We provide improved Standard Model theory predictions for the exclusive rare semimuonic processes $B \to K^{(*)} μ^{+} μ^{-}$ and $B_{s} \to ϕ μ^{+} μ^{-}$ . Our results are based on a novel paramet…

Dispersive bounds for local form factors in $Λ_{b} \to Λ$ transitions

Thomas Blake, Stefan Meinel, Muslem Rahimi +1

We investigate the ten independent local form-factors relevant to the $b$ -baryon decay $Λ_{b} \to Λ ℓ^{+} ℓ^{-}$ , combining information of lattice QCD and dispersive bounds. We propo…

Systematic Parametrization of the Leading $B$ -meson Light-Cone Distribution Amplitude

Thorsten Feldmann, Philip Lüghausen, Danny van Dyk

We propose a parametrization of the leading $B$ -meson light-cone distribution amplitude (LCDA) in heavy-quark effective theory (HQET). In position space, it uses a conformal transf…
