主 题:parity violation asymmetry parameters sensitivity spin density matrix angular distribution
摘 要:CP violation in baryonic decays has not been significantly *** large data events accumulated at e+e-colliders or the Large Hadron Collider,charmed baryon decays would provide a promising laboratory to test CP *** this study,we formulateΛ^(+)_(c)→ΦρandΛ^(+)_(c)→ωρdecays for the measurement of their asymmetry parameters in weak decays at the BESII or LHCb *** polarization transfer is analyzed in the two processes of e+e-→Λ^(+)_(c)Λ^(-)_(c)andΛ^(o)_(b)→Λ^(+)_(c)π^(-),and the formulas for the joint angular distribution of these processes are *** sensitivity of the measurement of the asymmetry parameters of the above two decay processes is estimated for future experiments.
