LHCb$1.625 \pm0.075 \pm0.221$ using ${\cal{B}}(B^+ \to K^+ K^- \pi^+)$0.00 Phys.Rev.Lett. 123,231802 (2019)LHCb uses a model of non-resonant obtained from a phenomenological description of the partonic interaction that produces the final state. This contribution is called single pole in the paper, see Ref.~\cite{Aaij:2019qps} for details.

Parameters of interest whose average is determined from individual measurements are called fit parameters. Parameters that are needed by the fit (in particular daughter branching fraction) and whose average is not determined here, but taken from somewhere else (usually PDG) are called external parameters.
