  Abstract An amplitude analysis of the Xi(+)(c) -> pK(-) pi(+) decay together with a measurement of the Xi(+)(c) polarization vector in semileptonic beauty-hadron decays is presented. The analysis is performed using proton-proton collision data collected by the LHCb experiment, corresponding to an integrated luminosity of 9 fb(-1). An amplitude model is developed and the resonance fractions as well as two- and three-body decay parameters are reported. A sizeable. thornc polarization is found. A large sensitivity of the Xi(c) -> pK(-)pi(+) decay to the polarization is seen, making the amplitude model suitable for Xi(+)(c) polarization measurements in other systems.
