  \(\Lambda^+_\mathrm{c}\) polarimetry using the dominant hadronic mode
abstract: |-
  The polarimeter vector field for multibody decays of a spin-half baryon is introduced as a generalisation of the baryon asymmetry parameters. Using a recent amplitude analysis of the (Lambda^+_mathrm{c} o p K^- pi^+) decay performed at the LHCb experiment, we compute the distribution of the kinematic-dependent polarimeter vector for this process in the space of Mandelstam variables to express the polarised decay rate in a model-agnostic form. The obtained representation can facilitate polarisation measurements of the \\(\Lambda^+_\mathrm{c}\\) baryon and eases inclusion of the \\(\Lambda^+_\mathrm{c} \to p K^- \pi^+\\) decay mode in hadronic amplitude analyses.
