We present a framework to analyze the effects of new physics beyond the standard model on B\ensuremath-B mixing and CP violation in B decays in a model-independent manner. Assuming that the tree level decay amplitudes are dominated by the standard model ones, new physics contributions to B\ensuremath-B mixing can be extracted from several measurements at B factories. Using this framework, we show the present constraint on new physics contributions to B\ensuremath-B mixing and illustrate the constraints expected to be given by future experiments at B factories. We also point out the possibility that CP asymmetries in B\ensuremath→\ensuremathψKS, B\ensuremath→\ensuremathπ\ensuremathπ, and B\ensuremath→DK modes look consistent with the standard model, even if a large new physics contribution is present in B\ensuremath-B mixing.
