Abstract EN
We consider what is the maximum information measurable from the decay distributions of polarised baryon decays via amplitude analysis in the helicity formalism.
We focus in particular on the analytical study of the Λc+⟶pK−π+ decay distributions, demonstrating that the full information on its decay amplitudes can be extracted from its distributions, allowing a simultaneous measurement of both helicity amplitudes and the polarisation vector.
This opens the possibility to use the Λc+⟶pK−π+ decay for applications ranging from New Physics searches to low-energy QCD studies, in particular its use as absolute polarimeter for the Λc+ baryon.
This result is valid as well for baryon decays having the same spin structure, and it is cross-checked numerically by means of a toy amplitude fit with Monte Carlo pseudodata.
