摘要
Polarization transfer measurement plays an important role in the search for new physics processes incharmed baryon decays.The measurement of the A^(+)_(c)→pK^(-)π^(+) decay is suggested asaspinpolarimeter.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 iswell determined usingaset ofMonte-Carloevents with selected asymmetry parameters.The experimental measurement of these asymmetry parameters is suggested.
