We argue that a small or large CP-violating asymmetry {\cal A}_{\psi K_S} in B^0_d vs \bar{B}^0_d --> J/\psi K_S decays, which seems to be favored by the recent BaBar or Belle data, might hint at the existence of new physics in B^0_d - \bar{B}^0_d mixing. We present a model-independent framework to show how new physics in B^0_d - \bar{B}^0_d mixing modifies the standard-model CP-violating asymmetry {\cal A}^{\rm SM}_{\psi K_S}. We particularly emphasize that an experimental confirmation of…
