Abstract: Sensitivity studies to the CP-violating parameters of the decay Bs->phi phiwith the LHCb experiment are presented. The decay proceeds via a b->s s anti-sgluonic-penguin quark transition, which is sensitive to contributions frombeyond the Standard Model particles. A time-dependent angular analysis ofsimulated data leads to an expected statistical uncertainty of 6 degrees on anynew physics induced CP-violating phase for a sample corresponding to 2 fb^{-1}of integrated luminosity. The expected precision on sin2beta from the relateddecay Bd->phi K0S is also discussed.
