Reconciling hadronic and partonic analyticity in $b \to s ℓℓ$ transitions

Martin Hoferichter, Bastian Kubis, Simon Mutke

Rare $B$ -meson decays mediated by $b \to s ℓℓ$ transitions constitute sensitive probes of physics beyond the Standard Model, and have triggered considerable interest due to hin…

Dispersive Analysis of $D$ - and $B$ -Meson Form Factors with Chiral and Heavy-Quark Constraints

Simon Mutke, Leon A. Heuser, Ingrid Dax +2

We analyze the isovector vector form factors of $D$ , $D^{*}$ , $B$ , and $B^{*}$ mesons at low energies. We employ all constraints due to chiral and heavy-quark symmetry, and include the…

Advanced parametrisations for hadronic form factors

Nienke C. Balz, Florian Herren, Bastian Kubis +2

The rich analytic structure of hadronic form factors makes a theoretically consistent yet easily applicable parametrisation cumbersome. Consequently, most parametrisations are limi…
