No, it is not correct.
First of all, you have to calculate the betacm from the initial particles (the target proton at rest and the projectile antiproton), and not from the supposed reconstructed lambdas.
Second, if your CM is traveling at betacm, in order to have the coordinates in the CM frame you have to boost them of -betacm.
