description Sensitivity Studies of chi and DeltaGamma with Bs -> Jpsi(mu+mu-)phi(K+K-) Using fast parameterized `toy' Monte Carlo experiments, the performance of LHCb to the parameters sin(-2chi), the amplitude of the mixing induced asymmetry in the channel Bs->Jpsi phi, and DeltaGamma/Gamma, the lifetime difference between the two CP eigenstates of the Bs system, is studied. For the expected Standard Model values of the relevant physics parameters, a sensitivity on sin(-2chi) around 0.064 and on DeltaGamma/Gamma of 0.018 is found using a sample corresponding to a single year of data.
