Abstract

We study

CP

violation in

\frac{J}{ψ} \to Λ \bar{Λ}

decay. This decay provides a good place to look for

CP

violation. Some observables are very sensitive to the

Λ

electric dipole moment

d_{Λ}

and therefore can be used to improve the experimental upper bound on

d_{Λ}

.

CP

violations in the lepton pair decays of

\frac{J}{ψ}

and

ϒ

are also discussed.
