摘要：
The angular distribution of l+l- in the decay of b --> sl+l- is studied. We point out that a large forward-backward asymmetry in the angular distribution of the dileptons is expected from the short-distance contribution in the standard model for a heavy top quark mass. The asymmetry is a measure of the contribution of the Z and W+W- exchange diagrams, as well as the top quark mass.
