Towards an amplitude analysis of the decay $Λ_{b}^{0} \to p K^{-} γ$

Johannes Albrecht, Yasmine Amhis, Anja Beck +1

The helicity formalism applied to the radiative decay $Λ_{b}^{0} \to p K^{-} γ$ is presented for the first time in this paper. The aim is to provide the necessary formalism to be able to re…

Probing flavoured Axions in the Tail of $B_{q} \to μ^{+} μ^{-}$

Johannes Albrecht, Emmanuel Stamou, Robert Ziegler +1

We discuss how LHC di-muon data collected to study $B_{q} \to μμ$ can be used to constrain light particles with flavour-violating couplings to $b$ -quarks. Focussing on the case of a…

Future prospects for exploring present day anomalies in flavour physics measurements with Belle II and LHCb

Johannes Albrecht, Florian Bernlochner, Matthew Kenzie +3

A range of flavour physics observables show tensions with their corresponding Standard Model expectations: measurements of leptonic flavour-changing neutral current processes and r…
