A sample of 400 000 candidates is selected from proton-proton collisions recorded by the LHCb detector at a center-of-mass energy of 13 TeV. An amplitude model is developed and the resonance fractions as well as two- and three-body decay parameters are reported. The mass and width of the Ao2000 thorn state are also determined. A significant A+c polarization is found. A large sensitivity of the A+c – pK-& pi;+ decay to the polarization is seen, making the amplitude model suitable for A+c polarization measurements in other systems. %R 10.1103/PhysRevD.108.012023 %U https://arxiv.org/abs/2208.03262 %U https://doi.org/10.1103/PhysRevD.108.012023 %P 012023-27pp
