| 英文摘要 | An enhancement of cross section for e(+) e(-) -> Lambda(+)(c)(Lambda) over bar (-)(c) pair production near their threshold provides an opportunity to study the charm baryon Lambda(+)(c)/(Lambda) over bar (-)(c) at a tau-charm factory with e(+) e(-) collisions. We estimate the prospects of searching for the CP violation in the decays Lambda c+ -> Lambda(+)(pi) and (Lambda) over bar (-)(c) -> (Lambda) over bar (-)(pi). Helicity amplitude analysis shows that the asymmetry parameters, alpha(+)(Lambda c) and alpha((Lambda) over barc-), can be directly accessed by looking at the angular proton and antiproton distributions in their helicity systems. A Monte Carlo estimation shows that data with the integrated luminosity of 530 pb(-1) yields a statistical precision of about 25% for the CP asymmetry parameter A. To improve the precision to better than 0.1%, an integrated luminosity of at least 1800 fb(-1) of data is required. |
