Using Lambda(+)(c) -> pK(-)pi(+) as a spin polarimeter

Polarization transfer measurement plays an important role in the search for new physics processes in charmed baryon decays. The measurement of the Lambda(+)(c) -> pK(-)pi(+) decay is suggested as a spin polarimeter. A general description of the decay is developed using Euler angles, and the polarization parameters are derived. Its relationship with parity violation is found using the phenomenological amplitude model. A Monte-Carlo simulation is performed, and the results show that charmed baryon polarization is well determined using a set of Monte-Carlo events with selected asymmetry parameters. The experimental measurement of these asymmetry parameters is suggested.
