Abstract

Measurements on the weak decay asymmetry parameters of charmed baryon, say Ξc\Xi_c, provide more information on the WW-emission and WW-exchange mechanisms controlled by the strong and weak interactions. Taking advantage of the spin polarization in the charmed baryon decays, we investigate the possibility to measure the weak decay asymmetry parameters in the e+eΞc0Ξˉc0e^{+}e^{-}\to \Xi_c^0\bar\Xi_c^0 process. We analyze the transverse polarization spontaneously produced in this process and spin transfer in the subsequent Ξc\Xi_c decays. The sensitivity to measure the asymmetry parameters are estimated for the decay ΞcΞπ\Xi_c\to\Xi \pi.
