A bstractRare b → sℓ+ℓ− flavour-changing-neutral-current processes provide important tests of the Standard Model of particle physics. Angular observables in exclusive b → sℓ+ℓ− processes can be particularly powerful as they allow hadronic uncertainties to be controlled. Amongst the exclusive processes that have been studied by experiments, the decay Λb → Λℓ+ℓ− is unique in that the Λb baryon can be produced polarised. In this paper, we derive an expression for the angular distribution of the Λb…
