"description": "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 $\\Lambda^+_\\mathrm{c} \\to p K^- \\pi^+$ 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.", | ||
