Abstract

The

CP

-violating longitudinal-polarization asymmetry

P_{L}

of the outgoing muon in

η \to μ \bar{μ}

and

K_{L} \to μ \bar{μ}

decays and the electric dipole moments of an electron and muon

d_{l}, l = e, μ

are studied in various extensions of the standard

CP

-violation model. The possibility of having large

P_{L}

in both decay and

d_{l}

is explored.
