DESCRIPTION:I will dicsuss the potential to observe CP-violating effects i
 n SUSY cascade decay chains at the LHC.  Asymmetries composed by triple pr
 oducts of momenta of the final state particles are sensitive to CP-violati
 ng effects. Due to large boosts these asymmetries can be difficult to obse
 rve at a hadron collider. If all particle masses in a cascade decay are kn
 ow\, it may be possible to reconstruct the decay chains on an event-by-eve
 nt basis even when we have missing momentum due to the LSP. After the reco
 nstruction\, the CP violating signal gets significantly enhanced and an ob
 servation may become feasible. The most important background and experimen
 tal effects have been included. I will show examples for light squarks and
  stop decay chains and a possible signal in Higgs boson decays.
