title = "Amplitude analysis of the Λc+ → pK - π+ decay and Λc+ baryon polarization measurement in semileptonic beauty hadron decays",
abstract = "An amplitude analysis of ?c+?pK-p+ decays together with a measurement of the ?c+ polarization vector in semioleptonic beauty hadron decays is presented. 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 ?(2000) state are also determined. A significant ?c+ polarization is found. A large sensitivity of the ?c+?pK-p+ decay to the polarization is seen, making the amplitude model suitable for ?c+ polarization measurements in other systems.",
