An enhancement of cross section for e+e− → Λc+Λ¯c− pair production near their.threshold provides an opportunity to study the charm baryon ¯ Λc+ Λc− at a τ-.charm factory with e+e− collisions. We estimate the prospects of searching for.the CP violation in the decaysΛc+ →Λπ+ and¯ ¯ Λc− →Λπ−. Helicity amplitude.analysis shows that the asymmetry parameters, c αΛ + and ¯c αΛ −, 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 . To improve the precision to better than 0.1%, an.integrated luminosity of at least 1800 fb−1 of data is required.
