We present results on B -> J/yKp decays using e+e-annihilation data collected with the BABAR detector at the U(4S) resonance. The detector is located at the PEP-II asym.-energy storage ring facility at the Stanford Linear Accelerator Center. Using approx. 88*106 B-B pairs, we measure the decay amplitudes for the flavor eigenmodes and observe strong-phase differences indicative of final-state interactions with a significance of 7.6 std. deviations. We use the interference between the Kp S-wave and P-wave amplitudes in the region of the K*(892) to resolve the ambiguity in the detn. of these strong phases. We then perform an ambiguity-free measurement of cos2b using the angular and time-dependent asymmetry in B -> J/yK*0(KS0p0) decays. With sin2b fixed at its measured value and cos2b treated as an independent parameter, we find cos2b=2.72-0.79+0.50(stat)+-0.27(syst), detg. the sign of cos2b to be pos. at 86% C.L. [on SciFinder (R)]
